What power! You peer review yourself. In common terms, you're a mental masturbator. John Anderson I feel, you are font of this paper. You have no other arguments and you understood what is your own knowledge of pitecantrop worthy. I realize that English may not be your native language. But I can'trespond to something that is not only incoherent, but which contains stuff like "pitecantrop worthy" which seems to be your own creation. John Anderson John, Had you an intention to respond sensibly? ;-) Seemingly, you began accusing me of self-reviewing and brought to NG the lexicon of cheap pubs. True, I don't know, do you grasp the difference between the abstract and review? ;-) I can say only, this is not your invention - to clutch at the slip of opponent's pen, while understanding full lack of own arguments. Yes, I was grammatically mistaken (the meaning remained clear) - was it so important as your prejudice and cheap jargon in communication with a colleague? Would you first learn the ethics of behaviour, then learn a little the methodology of physics, then get in discussion with your hoofs. You talked about "in our journal "SELF Transactions". I responded to two things, "our" and "SELF". It sounds like you were using the royal we and talking about your private journal. The term SELF only reinforced that. If this "journal" only takes abstracts, which your present post seems to imply, then it isn't a reviewed journal Which is what I was saying that you implied. You're not a colleague of mine, my friend, you're a crank. John Anderson John, what will you think out next? ;-) Of course, you haven't visited our journal and didn't see, the paper has two authors, and SELF is the name of our laboratory (Special Laboratory for Fundamental Elaboration). Poor baby! They have put him in a dark corner of internet and didn't explain how to activate hyperlinks! But they had no necessity to teach a baby, how to mud other's work. Anyway, you of course cannot distinguish full text from the abstract and don't know, what are the reasons of refereeing process: to check, (a) is the manuscript within the scope of journal; (b) the novelty of material; (c) is the proof correct; (d) is the material written and presented well. Thus, should you really be my colleague physicist, you would enter our journal and see, this is really the journal of our laboratory, so (a) is satisfied. You would learn to read and would see, no one never conducted such studies and obtained such results - this means, (b) is also satisfied. You would reach the item 4.4 of the mentioned paper and see, the calculations WE made on the basis of OUR phenomenology of phenomenon are fully consistent with the experiental data; this is the most weighty proof of correctness in physics. When bad boys from QM try telling you, one phenomenon can be substantiated in different ways, don't believe them. To begin with, try to imagine another description of our experiment with the single conductor, but so that it were consistent with the experimental results. Cannot you? So (c) has been also satisfied. And (d) is satisfied automatically, as this actually is our private journal. Should you be really the physicist, you would concentrate on the material, not on the detail, has it such oafish referees as you are which cannot match two words in their own language, and you would not make a tragedy of shortcomings of our translation but would be grateful that we have translated this material for you from the language you don't know into your native. And as far as you have not been taught even to such elementary things, all your attempts to find fault in the things you never saw can raise only my symphathy to the corner where 'they' have put you in the internet. Poor baby, don't cry, your head is not fully quadratic, only there where your single convolution bulges out. Don't try to butt with it, baby, or the last will ossify into a horn. ;-) Sergey. |

Hello,
A simple experiment using an AC coil, rod to fit inside of coil, and several washers that fit the rod, seems to contradict your evidence. Using aluminum for the washers and steel for the rod, when AC electricity is applyed to the coil, the washers will seem to float on the rod. The strength of the field and the mass of the washers determines where the washers will move to. Although the experiment is used to demonstrate dimagnetic materials, it also suggests that magnetic lines of force are not open. As a thought experiment, what would happen if the earth spewed lines of magnetism from it's axis. We would not have a clear astronomical vewing that is found at the north pole. The magnetic lines of force would probably distort viewing of stars. This is my view on the subject. I refuse to use existing formulas to explain the subject, because they are not conclusive one way or another. This is one of the problems with convential thought of electromagnetics. Another disclaimer, I am not trying to suggest any changes to convential thinking, only to offer a discussion point on this subject. If I have not interperated your conclusions properly, please clarify your position. |

Dear Sergey, I read your paper, but....I am very sorry to bring you bad news.In my opinion it's all wrong, horribly wrong. I urge you to withdraw your paper from Internet. I have no problem with your introduction; also not with your equations and not even with your experiments. But I noticed a big misunderstanding with the application of the equations. In short: 1. The induction according to standard theory is not related to the change of B vector at the wire, but to the change of enclosed flux, that is, to the total amount of change of field lines inside the enclosed area. 2. When you go from an infinitely small area loop to a closed wire that you measure at each end you change the configuration into something different from what you think. In fact you create a loop of which one part is that piece of wire and the rest is your measurement system that closes the loop. All in all, as far as I can see you measured nothing unusual, some of your results I foresaw before reaching your data, and most or all other results are easy to explain. I propose to discuss details by personal email. Sincerely, Harald "Sergey Karavashkin" wrote in message om... Dear Colleagues, We published a new paper " Several experiments studying dynamic magnetic field " in our journal "SELF Transactions", volume 3 (2003), issue 1 *Abstract* We substantiate three sets of experiments studying EM induction, describe and present their results.

If I have not interperated your conclusions properly, please clarify your position. Dear Bob, Thank you for a very interesting questions. I'm answering with pleasure. Only first I would ask you, please don't take offence where I'm saying your point erroneous. I mean no attempt to sting you but simply indicate, where the inexact judgement takes its root from the conventional ideas of magnetism. ;-) I'm also pleased to tell you, we appreciated your very important questions and made of your post and of my respond an appendix to our paper. Please find it at http://angelfire.lycos.com/la3/selft...ents3.html#bob There I was able to illustrate my respond with pictures which also can be interesting for you. So you can read it here or in our journal. In your post you oppose to our experiments another experiment with levitating rings. You surely have read our paper to the end and noticed, throughout the paper we oppose stationary and dynamic fields. Stationary field has closed lines of force, and dynamic field has them open. But there is one aspect that did not appear in the paper. It begins with the question, how the alternating magnetic field of the primary circuit affects the currents in secondary circuit? The answer suggests itself: it affects just as stationary magnetic field does. But the field of which we are speaking is dynamic. Yes, indeed. This is just the feature which you perceived in the experiment with levitating rings. The dynamic field of which we are speaking in our paper is the induction field, and the field revealing in interaction of currents is relevant to Ampere law. These are two different fields! The first field EXCITES currents in the secondary circuit, and the second field is able only to affect already existing currents. So, when we in our paper compared dynamic magnetic field (induction field) with stationary magnetic field, we essentially limited the comparison, indeed. We had to limit, knowing by our bitter experience, how much the brains of today physicists are "switched off". They didn't understand even in this simplified form. So hearing your question, I'm glad as seeing the sun from louring sky. Thank you again. Having understood this feature, you will easily explain the experiment with levitating rings. The current in the primary coil orients the molecular currents in the ferromagnetic rod. With it the magnetic forces in the coil and rod are added. But along the rod, the magnetism decreases from the coil to the end of rod. So, if the rod is very long, its end is known to do not attract the irons. The current excited in the ring by molecular currents in the rod is OPPOSITE to these currents - this means, also to the current in the coil; so the ring will be pushed out from the coil to the end of rod, creating the effect of levitation. If we take a coil with a thick wire and powerful oscillator of low-frequency signals, and feed to this coil an alternating voltage of few Hertz frequency (or rather even a fraction of Hertz), we will see the coil not simply "floating up" but vibrating on the rod! This occurs due to the dynamics of vibration processes. The matter is, with sinusoidal current at its low frequency, during a part of period the gravitation attraction will be more than the buoyant force in amplitude, and this will cause the ring some falling; during the rest part of half-period this falling will compensate, wherethrough vibrations arise. We can avoid them, placing the coil with the rod horizontally. And to avoid friction, we can hang the rings on to a long thread. In this case we will see the rings only pushing out to the end of rod. I would like to draw your attention that the rings of aluminium will be just pushed out to the end of rod corroborating the opposite direction of induced currents. In order to develop the experiment you have suggested, I would like to recall the paper by Laurence Hecht "To Be, or Not to Be Or, How I Discovered the Swindle of Special Relativity" http://21stcenturysciencetech.com/edit.html which I recently reviewed having been asked by Aleksandr Timofeev in sci.physics, thread "Gravitation and Maxwell's Electrodynamics, BOUNDARY CONDITIONS", my post to him of 2003-11-21. In that paper the author some changes the experiment in which the conductor with the current moves along the rails with the current (so-called relsotron). See the standard diagram of this experiment in Fig. 1. Instead the copper conductor, the author took it of steel, with it the direction of motion has changed. Among other things, I showed to the author that in this case we see two effects at the same time. The first effect is the interaction of currents in rails and current in conductor. The second effect is the interaction of magnetic field in the ferromagnet with magnetic field of the current in rails. The first effect conditions the change of direction of motion of conductor when the current in rails changed, and the second effect is one-directed. Then the diagram shown in Fig. 1 will change and take the appearance shown in Fig. 2. Just this effect takes place in case if you change the aluminium rings by those of steel. With it in the steel ring there will excite both the inductive current and induced magnetism (orientational)! The force caused by the induction current will push the ring out, and orientational magnetism will attract the ring to the coil. The balance of these forces will provide the resulting force which in case of steel ring will be directed towards the coil. We can easily check the presence of two forces affecting the steel ring by the following experiment. Take a rod, put on it a coil and place them horizontally, as we see it in Fig. 3. Cut the steel ring across its cross-section and solder to the boundaries of gap flexible COPPER taps, then hang the coil on to a long thread. Naturally, the ring will deviate towards the coil. If now we register this deviation and close the taps, this deviation will diminish! ;-) Such is my position in this subject, and it doesn't contradict the results we have obtained in the paper. The experiment you have suggested from the conventional point of view cannot tell us of the open lines of force of magnetic field; as you see from the said above, levitation is provided by the orientational magnetic field whose lines of force are closed. Or rather, in the representation understandable now, this is so. The same, the Earth never can spew the lines of force of ORIENTATIONAL magnetic field, so don't worry of our clear astronomic vision. Another thing, we still have unstudied or poorly studied too many things concerning celestial bodies. In particular, we described some features of star magnetic field formation in the first part of chapter 2 of our monograph "Some aspects of the Earth evolution" http://selftrans.narod.ru/v3_1/chapt...a67/c2a67.html Of course, this is far from all necessary for complete understanding of these processes, and we are going on studying them in the next parts and chapters. But this beginning shows that magnetic field doesn't separate from the body, but in case of hot body there forms a double magnetic "cocoon", and magnetic force lines of the core of star are "embedded" by the external field. I would like to mark especially, when speaking of embedded lines of force of magnetic field, I in no case suppose any force that would affect the lines of force. These lines are the fiction introduced by Faraday to make the field conveniently visual, so nothing can physically affect this fiction, as the fractal theory supposes. The lines of force simply show the direction of the force action at a definite point of space, nothing more. In presence of several fields in space, the trial body is affected by the resulting force dependent on the space distribution of these fields. So at a definite region of space there will dominate one field, and at another region - another field. Naturally, if we compare the pattern of force lines in each region where one of fields dominated, with the distribution of lines of force in case when the second field was absent, we will have an impression that the lines of force are "compressed", though factually nothing of the kind will take place. Such representation of compression is especially intensively developed by supporters of relativistic conceptions, though it is a roughest mistake in physics. If speaking of our work on magnetic field of stars, I would draw your attention that colleagues here fully ignored our advertisement of this paper, though the counter on our web site turns round as a fan, and should Angelfire not diminish the number, by our checked data, there would be already not 300 but no less than 3000 visitors. ;-) In particular, 423 colleagues have visited these two last papers during last four weeks, and we still have in average about 10 visitors daily. But my threads here keep silence, except idle squabbling like with John Anderson. ;-) This is the reason of my caution of which I told you above. However the corollaries of our experiments are vast. They fully change the conception of interaction of charges with magnetic field and have a great practical application. True, for it one has to know things well ahead than we wrote in this paper... ;-) I hope, I answered your questions, and I'm ready to keep the discussion up in order you to understand better. Kind regards, Sergey. |

I propose to discuss details by personal email. Sincerely, Harald Dear Harald, Some time ago I explained you, I have the internet access twice a week. Once I can take your post, and another time I can load my reply. So please have a patience and find my respond here http://selftrans.narod.ru/v3_1/b/harry/harry.html with figures, or read here as a simple text: Dear Harald, Unfortunately, I still don't see the reasons to be upset, neither to withdraw this paper from the web. You are saying yourself, I have no problem with your introduction; also not with your equations and not even with your experiments. Is not it principal, as from it all other follows. ;-) Now in turn. 1. You are stating, The induction according to standard theory is not related to the change of B vector at the wire, but to the change of enclosed flux, that is, to the total amount of change of field lines inside the enclosed area. As far as I know, you always read attentively and could not disregard that when we described the standard representation, we emphasised this point too. Otherwise, why had we to put Fig. 3 into page 74 of our paper? ;-) The difference between vector B variation and variation of flux of vector is insufficient in case of stationary loop and unchanged position between loops, as at constant cross-section and position of secondary loop (just the case of our experimental study), the flux variation is tantamount to the vector variation. Have you another opinion? ;-) Right away I would answer your next question which you did not ask: how much limited is the studied statement of problem? I can assure you, from the obtained results the most general corollaries follow. Simply we should take into account the known fact that the experiment is always carried out at the conditions at which the properties of studied phenomenon reveal in the most visual way. Just this stipulated the scheme of experimental techniques. With mutually moving loops or varied cross-section of loops in the course of experiment, there would always be present factors of variation of density, or cross-section, of flux which would actually blur the pattern, not allowing to conclude provably. By this reason we chose for the first experiment the construction of air transformer with the internal and external secondary windings. If you look at Fig. 4 of the paper, page 75, where we showed the lines of force of magnetic field in standard representation, you will see, for the internal winding the flux is directed upwards, and for external winding - downwards the figure. Now please determine the direction of induced currents on the basis of standard representation and make sure, they have to be directed oppositely. But you see, they are one-directed. Now try to close these lines of force. ;-) Thus, the obvious results (as you write) are not so much obvious in the view of conventional formalism. True, here exists one more merely virtual possibility - to invert the vector of cross-section of secondary loops. However, if you try to do so, I will simply suggest you to conduct a set of experiments shown here in Fig. 1. Fig. 1. Experiment with sequentially increasing cross-section of secondary loop (blue) from the enclosed into the primary loop (a) to the embracing it (d). The primary loop is shown in red. You see in this figure, in each next experiment the cross-section of secondary loop some increases, gradually transiting from the enclosed loop to that embrasing. If you think these four steps not enough, you can increase the number of intermediate experiments. The main aim is, you would be able to conclude surely, when exactly the direction of vector of the loop cross-section changes. ;-) And I would like to notice, if you carry out all these experiments at the same time, you would obtain just the result as we obtained in our first experiment for all connected loops. If you are able, none the less, to reveal the moment when the secondary loop inverts, I will sent you a chocolate sweet. ;-) Then I would suggest you to conduct an experiment with the secondary winding reeled up BETWEEN the turns of primary winding, as it is shown here in Fig. 2. Fig. 2. Experiment with the air transformer made by reeling up the secondary winding (blue) between the turns of primary winding (red) As you can see in this figure, if you think the force lines of magnetic field close (lilac circulation arrows), where the turns of secondary winding are located, the magnetic fields are subtracted, - consequently, emf will not be induced at all. But you know, this is not so, though the technique based on mutual subtracting of magnetic fields is quite standard. It is used, for example, to determine the resulting field of molecular magnets. You see, the experiment described in our paper is far from being only, and everywhere we see one and the same problem closed lines of force of induction. Open them and everything takes its place. And you are saying, we showed nothing new in our experiments. Are you surely unbiased here? This is just the aspect that you and other colleagues didn't want to see when I multiply suggested you: read and analyse the conservation laws for dynamic fields that we have proven and published for you. You all brushed aside, though I said, you can brush aside or take offence, but the nature is such as it is. Ignoring its regularities, you would stop to be physicists, nothing more. Thus, you could expect the result in view of practice, not in view of existing phenomenology. Again, when the theses have been proven and the points made, everything is so simple and obvious, but by some reason I didn't see such approaches before neither from you nor from others. You see, this undoubtedly is a discovery that essentially changes the very idea of magnetic fields. Even when I said you, the heart of interaction in magnetic field has not been taken into account finally, you also brushed aside (or rather, you left my words without answering). If now you are saying, nothing new in it, would you tell us, what will be the next step in cognition of this regularity? I will send you a second sweet! ;-) Especially I would like to touch the force lines within the selected region. As is known, in all field diagrams you draw the distribution of momentary force lines of the field. If you said, the matter is only in changing density of lines of force, how can you understand the density of these lines when the flux changes direction? You know, flux changes not only its value but direction too, does not it? ;-) 2. Your second question is more interesting, though we much enlightened it in our paper. An attempt to represent the taps from probe in the gap as the continuation of loop is quite natural and we though of it when developed the technique of second experiment. Having read the technique of second experiment in the item 2.2, page 79, you should draw your attention to the features about which we said in that item. First, as you can see from Fig. 11, out of region of measurement, the field is localised at the core and in both rods has the same direction of momentary field of vector B. Second and the main, the taps of frame shown in Fig. 12 of paper, page 79, embrace both lateral rods of the core and are placed quite far from them. You can easily make sure from the construction shown in Fig. 3 here that the induction emf in taps is directed oppositely this means, it is subtracted! Fig. 3. General appearance of measuring frame in the gap of core Thereupon we measure only emf that is induced in the central rod of frame. Now let us consider, how the loop transforms from round to ellipsoidal shape. When you are stating, When you go from an infinitely small area loop to a closed wire that you measure at each end you change the configuration into something different from what you think. you are a bit inexact. If the field was localised in some region of space - and just this stipulated the transition from compressed loop in Fig. 9 of paper to the single wire in Fig. 10 in the same page 78, - then the taps are located out of the region of field. Have you paid no attention to this point? You have an opportunity to do so. ;-) If we add to it a compensation measuring frame, nothing to say of closed loop. You can otherwise make sure in what I'm saying. It would be enough to change the frame a little, adding to it the second central wire, which we should make movable, as opposite to the first, as it is shown in Fig. 4. Fig. 4. Circuit with the two-path central conductor In this circuit, if in the beginning of experiment both conductors are equally distanced from the axis of gap, then, really, total emf will be zero. This additionally checks the fact that the taps have no effect on the measurement. When we move the movable conductor towards immovable, according to conventional phenomenology, the inductive emf cannot appear, as we still measure the difference in voltage between the opposite points of closed loop. Moreover, the cross-section between the conductors diminishes. But really emf will appear and grow with diminished distance between conductors, because symmetry of location of conductors as to the axis of gap will be disturbed the more the closer will they be located to each other. True, the value of this emf will be first very small, as each rod is short-circuited to the second rod, and emf in them directed oppositely. But we can increase it, making the conductors of high-Ohm material for example, of constantan, with a small cross-section. This will not change the difference between the phenomenologies of expected effects, but measurements will become well easier. But even out of it, even if you take conductors of copper, in transition of movable conductor through the gap axis the total emf will abruptly increase, as emfs in the arms will be already one-directed, only will have different amplitudes. We simply have to account that, because the conductors are mutually closed, emf will grow nonlinearly with decreasing distance between the conductors. When the conductors coincide, emf will be maximal! At minimal cross-section of loop, from the viewpoint of conventional phenomenology! And you are saying, flux of vector! Which flux of vector will be in coincidence of conductors? So I still see not a least reason to withdraw our paper or to pass to an underground discussion. We already had an underground discussion, and you disappeared just at the moment when understood me right. You would first induce in correspondence with the laws of nature, not towards the salvage of rotten dogmata. It would be more useful and productive. I told you, but you did not believe… Regards, Sergey. |

As far as I know, you always read attentively and could not disregard that when we described the standard representation, we emphasised this point too. Otherwise, why had we to put Fig. 3 into page 74 of our paper? ;-) Indeed, at that point, it looked like you understand it perfecly well. Now it looks like the meaning of "field lines inside enclosed area" is not understood by you. The difference between vector B variation and variation of flux of vector is insufficient in case of stationary loop and unchanged position between loops, as at constant cross-section and position of secondary loop (just the case of our experimental study), the flux variation is tantamount to the vector variation. Have you another opinion? ;-) Here a good understanding of what you mean may be important. If I understand you well, then yes, I do have a very different opinion! The phrase in your paper that I do understand for su "Thus, if the conventional treatment of induction is true, the phase shift between the ... interior and exterior secondary loops has to be equal to 180 degrees." That is where I got a sick feeling in my stomach, for that is certainly not the case, as set out in fig.3, the phase shift must be 0 degrees! SNIP If you look at Fig. 4 of the paper, page 75, where we showed the lines of force of magnetic field in standard representation, you will see, for the internal winding the flux is directed upwards, and for external winding - downwards the figure. Again, NO! The direction of the lines of force is not equal to the direction of the net enclosed flux. In fact it was useful in a way to be confronted with it in this way, as more clearly than in the past I realise how non-local the effect is - quite magical without an ether theory. To say it in plain English: in conventional electromagnetic theory, the local magnetic field vector change is irrelevant for the induced current. What counts is the average magnetic field inside the loop, and not the magnetic field at the wire. It very much looks like you confused a line integral with a surface integral. :-( To put the equation in another way, with V =voltage, S = surface and B' = average magnetic field inside the loop: V = S * dB'/dt . In your fig.4 the secondary windings enclose about the same amount of flux, in fact it may be perfectly the same as the surface that the outer one has more than the inner one, contains about an equal amount of upward and downward flux. Now please determine the direction of induced currents on the basis of standard representation and make sure, they have to be directed oppositely. Again: No! But you see, they are one-directed. Now try to close these lines of force. ;-) And lines of force at a wire are independent of magnetic induction in the wire... This is where I stop now, for as long as this is not cleared up, it is useless to discuss the other, strongly related points; and when it is cleared up, most other points will become clear. Sincerely, Harald Dear Harald, You have snipped all my explanations and make appearance as if there was nothing in my post except you retained. Well, I will not comment it, but in order to lift finally the question of flux of vector that you are imposing and to show you your statement erroneous and related to the conventional electromagnetic theory only in your mind: in conventional electromagnetic theory, the local magnetic field vector change is irrelevant for the induced current. What counts is the average magnetic field inside the loop, and not the magnetic field at the wire I suggest to carry out a very simple experiment shown in Fig. 1which you can see with this text at http://selftrans.narod.ru/v3_1/b/harry2/harry2.html Fig. 1 Take two cores of the same material and assemble them so that their cross-sections be equal but as if turned perpendicularly relatively each other. On these cores, reel up the windings with equal number of turns of wire having the same diameter. The width of gap is also the same in both cores, and one source serves for both. Thus, the only difference between them will be that one plane of cross-section is turrned as to another. To check the cores identity, we can measure their inductance. If we made this all carefully, it has to be in limits of very small error (1 2 %). Let us also make a frame WITHOUT compensation (usual loop with large perimeter) so that its size was much more than the size of cross-section of loop. Insert the frame into the gaps of cores so that in both cases its rod in the gap was exactly at the interior boundary of gap. Thus, in both cases the cross-section of flux going through the secondary circuit is the same and this flux will average (your personal invention) equally across the section, isn't it just your statement? To put the equation in another way, with V =voltage, S = surface and B' = average magnetic field inside the loop: V = S * dB'/dt . I would like to notice here, I'm intentionally saying of a large size of frame, as in this case the difference in average across the cross-section of gap will be very, very negligible. Now let us experiment. You already have guessed, in this circuit, with the frame having constant cross-section, being immovable relatively core and at constant cross-section of gap, you have to yield the inductive emf the same in both gaps, and my emf has to dependent on ratio between the long and short sides of gap. To lift all additional doubts because of dispersion, let us make this ratio considerable - for example, 1/3 or 1/4. So, even with all your distrust, the difference between our results will be trustworthy sufficient. Are you ready to check it and make sure? ;-) Sergey. |

See below; I intertwine some of your comments with mine.
"Sergey Karavashkin" wrote in message om... (Harry) wrote in message . com... (Sergey Karavashkin) wrote in message om... "Harry" wrote in message ... SNIP Dear Harald, Some time ago I explained you, I have the internet access twice a week. Once I can take your post, and another time I can load my reply. So please have a patience and find my respond here http://selftrans.narod.ru/v3_1/b/harry/harry.html with figures, or read here as a simple text: Nice picture! And this one is very clear, even without text. Dear Harald, Unfortunately, I still don't see the reasons to be upset, neither to withdraw this paper from the web. You are saying yourself, I have no problem with your introduction; also not with your equations and not even with your experiments. Is not it principal, as from it all other follows. ;-) No, not even in two postings I was able to communicate to you what the problem is... despite that in my comments I SNIPPED away most of the thigns that are irrelevant to my objection! In order to keep it compact, I will again remove most of what is not necessary or even confusing, so that the emphasis will be right Now in turn. 1. You are stating, The induction according to standard theory is not related to the change of B vector at the wire, but to the change of enclosed flux, that is, to the total amount of change of field lines inside the enclosed area. SNIP The phrase in your paper that I do understand for su "Thus, if the conventional treatment of induction is true, the phase shift between the ... interior and exterior secondary loops has to be equal to 180 degrees." That is where I got a sick feeling in my stomach, for that is certainly not the case, as set out in fig.3, the phase shift must be 0 degrees! SNIP If you look at Fig. 4 of the paper, page 75, where we showed the lines of force of magnetic field in standard representation, you will see, for the internal winding the flux is directed upwards, and for external winding - downwards the figure. Again, NO! The direction of the lines of force is not equal to the direction of the net enclosed flux. In fact it was useful in a way to be confronted with it in this way, as more clearly than in the past I realise how non-local the effect is - quite magical without an ether theory. To say it in plain English: in conventional electromagnetic theory, the local magnetic field vector change is irrelevant for the induced current. What counts is the average magnetic field inside the loop, and not the magnetic field at the wire. It very much looks like you confused a line integral with a surface integral. :-( - You did not comment on that; but it is perhaps the main point! Instead of explaining your understanding on what Faraday claimed, you now replied: I suggest to carry out a very simple experiment. [see further] Although it may be enlightening to know what really happens, it will in principle not help to solve the question about what the law of Faraday (I think it was him) predicts! But in practice it may be useful, in another way. To put the equation in another way, with V =voltage, S = surface and B' = average magnetic field inside the loop: V = S * dB'/dt . Thus, in both cases the cross-section of flux going through the secondary circuit is the same and this flux will average (your personal invention) equally across the section, isn't it just your statement?. Again, your comment is as part of an experiment to perform, and not about the theory. But you nearly correctly understood me: My "personal invention" about the meaning of a surface integral is that it gives you the total (normal) flux that is enclosed by the loop -done by multiplying the local B in the area with the dx and dy - and that is the same as the average (normal) B times the surface inside the loop. SNIP I suggest to carry out a very simple experiment shown in Fig. 1which you can see with this text at http://selftrans.narod.ru/v3_1/b/harry2/harry2.html Fig. 1 Take two cores of the same material and assemble them so that their cross-sections be equal but as if turned perpendicularly relatively each other. On these cores, reel up the windings with equal number of turns of wire having the same diameter. The width of gap is also the same in both cores, and one source serves for both. Thus, the only difference between them will be that one plane of cross-section is turrned as to another. To check the cores identity, we can measure their inductance. If we made this all carefully, it has to be in limits of very small error. Let us also make a frame WITHOUT compensation (usual loop with large perimeter) so that its size was much more than the size of cross-section of loop. Insert the frame into the gaps of cores so that in both cases its rod in the gap was exactly at the interior boundary of gap. Thus, in both cases the cross-section of flux going through the secondary circuit is the same and this flux will average (your personal invention) equally across the section, isn't it just your statement? I would like to notice here, I'm intentionally saying of a large size of frame, as in this case the difference in average across the cross-section of gap will be very, very negligible. Now let us experiment. You already have guessed, in this circuit, with the frame having constant cross-section, being immovable relatively core and at constant cross-section of gap, you have to yield the inductive emf the same in both gaps, and my emf has to dependent on ratio between the long and short sides of gap. To lift all additional doubts because of dispersion, let us make this ratio considerable - for example, 1/3 or 1/4. So, even with all your distrust, the difference between our results will be trustworthy sufficient. Are you ready to check it and make sure? ;-) Now, here is again the confusion between "you" and "my": I don't have my own theory. I thought that the purpose of your paper was to compare two theories in practice. In your paper you claimed that the test results are not according to the standard theory, while I noticed nothing different from expectation. And you did not directly reply to that. However, in your newly proposed experiment, clearly you predict something else than the books: You claim that the induced voltage is not determined by the amount of enclosed flux, but by the amount of magnetic field on the wire, and you propose the new experiment to decide. Am I right? I think it's a good idea, and your set-up looks OK to me. You can simplify the experiment by only using the second configuration, and move the loop along the air gap, starting from outside. In standard theory, the voltage should increase until you enclose all flux, after which it should be constant; while in your theory, it should remain constant until you enclose all flux, after which it should drop. Am I right? Nevertheless, it would be extremely surprising if you are right: not only *someone* would have noticed the above effects by now. Worse, doubling the circumference of a loop in a homogenous field is expected to result in 4 times as much voltage, while according to your hypothesis it results in only twice as much voltage (if I am wrong about your prediction, please elaborate). I think that such a thing is impossible to "miss"! All the best, Harald |

What counts is the average magnetic field inside the loop, and not the magnetic field at the wire. It very much looks like you confused a line integral with a surface integral. :-( - You did not comment on that; but it is perhaps the main point! Why, figures that you liked have commented. I especially choose the circuits showing that just the average field is irrelevant. Further I will broaden this theme a little. Instead of explaining your understanding on what Faraday claimed, you now replied: I suggest to carry out a very simple experiment. Right. Because namely in this experiment lies the answer to your question and my understanding of Faraday. [see further] Although it may be enlightening to know what really happens, it will in principle not help to solve the question about what the law of Faraday (I think it was him) predicts! But in practice it may be useful, in another way. See, Harald, for complete understanding of induction processes we have to pass a definite way. This what you read in our paper shows the entrance into the labyrinth but not the final output. Faraday whose heritage were experiments, not formulas, worked with loops and coils, so he described them. Maxwell and then hertz have formalised Faraday's experiments and fixed in formulas his experimental results. When you read our paper, you could see, we paid much attention just to, how to avoid loops, to see, how the induction law transforms in absence of loop. This was the main goal. Simply you shouldn't expect everything at once from one paper, then that what we have done will be more clear. ;-) To put the equation in another way, with V =voltage, S = surface and B' = average magnetic field inside the loop: V = S * dB'/dt . Thus, in both cases the cross-section of flux going through the secondary circuit is the same and this flux will average (your personal invention) equally across the section, isn't it just your statement?. Again, your comment is as part of an experiment to perform, and not about the theory. But you nearly correctly understood me: My "personal invention" about the meaning of a surface integral is that it gives you the total (normal) flux that is enclosed by the loop -done by multiplying the local B in the area with the dx and dy - and that is the same as the average (normal) B times the surface inside the loop. You see, Harald, numerical coincidence of results is stipulated by theorems, and the main, by vector algebra transforms, but electron of secondary loop cannot know what occurs out of particular physical point where it is located. When you are saying of the flux of vector crossing the loop, you conventionally do not ponder that the very idea of force line means the tangent to the direction of force action or to the field strength at PARTICULAR point. Usually, when we consider the flux of vector, we rarely make this flux inhomogeneous in cross-section. In this way we close the door to comprehend the phenomenon. This is why in the circuits of my previous message I formed just inhomogeneous field in the loop. You clearly see from it that, when averaging the flux of vector across the section, you lose the essence of processes of induction interaction. But if you do not average, then a number of questions arise which we study in our paper. You are right, there is no new theory in our paper. But who prevents us to create a team, to appeal for funding and to advance step by step into the depths of labyrinth? Is not it a standard practice in scientific circles? ;-) SNIP I suggest to carry out a very simple experiment shown in Fig. 1which you can see with this text at http://selftrans.narod.ru/v3_1/b/harry2/harry2.html Fig. 1 Take two cores of the same material and assemble them so that their cross-sections be equal but as if turned perpendicularly relatively each other.

Thus, the only difference between them will be that one plane of cross-section is turrned as to another. To check the cores identity, we can measure their inductance. If we made this all carefully, it has to be in limits of very small error. Let us also make a frame WITHOUT compensation (usual loop with large perimeter) so that its size was much more than the size of cross-section of loop.

You already have guessed, in this circuit, with the frame having constant cross-section, being immovable relatively core and at constant cross-section of gap, you have to yield the inductive emf the same in both gaps, and my emf has to dependent on ratio between the long and short sides of gap. To lift all additional doubts because of dispersion, let us make this ratio considerable - for example, 1/3 or 1/4. So, even with all your distrust, the difference between our results will be trustworthy sufficient. Are you ready to check it and make sure? ;-) Now, here is again the confusion between "you" and "my": I don't have my own theory. I thought that the purpose of your paper was to compare two theories in practice. In your paper you claimed that the test results are not according to the standard theory, while I noticed nothing different from expectation. And you did not directly reply to that.

Worse, doubling the circumference of a loop in a homogenous field is expected to result in 4 times as much voltage, while according to your hypothesis it results in only twice as much voltage (if I am wrong about your prediction, please elaborate). I think that such a thing is impossible to "miss"! All the best, Harald Everything what you saw in that new experiment has been fully presented in those which we stated in the paper. To show it, I suggest to refine a little the experiment from my previous post. Let us extend the loop from the gap, in any core. Factually this will be the same as in second and third experiments of paper. With it the rod of loop in the gap will be in the field shown in figure that you can see at http://selftrans.narod.ru/v3_1/b/harry3/harry3.html Fig. 1 In this figure you see the cross-section of rod of loop (red circle) in two extreme locations. You see that during the displacement the direction of instantaneous magnetic field in the gap does not change. Only the frame comes out of the gap. And during going out of gap, the direction of instantaneous flux of vector B that crosses the cross-section of frame also will not change, changes only the absolute value of your dear "average flux". Thus, on whatever variation of standard formalism would you rely, you will not get the inversion of flux with the loop coming out of gap. At the same time the experimental results will show you the same inversion of emf at the centre of gap as in the second experiment of paper. This means, not everything in the paper is so much expectable? ;-) Simply you would analyse these results deeper, in particular the condition of compensation of parasitic emfs in the loop. Instead to do so, you snipped the substantiation from my before-last post with Fig. 3 as irrelevant. I'm inserting this figure again. Fig. 3 from the previous post In this figure you can see the frame just compensative and that it allows to measure just the inductance in the rod, not in the loop. Though in the paper we showed, it is unnecessary to apply the compensative frame. Simply we have to fulfil few conditions (this is what I'm adding now). The first condition has been indicated in the paper - this is localisation of magnetic field. Second condition is visual from the experiment of my previous post which puzzled you this is the location of taps as far as possible from the rod of core. The compensative construction of frame only provides the reliability of measurement but is not necessary if these conditions have been fulfilled. You have skipped this all, and now you are saying, you don't understand. Naturally. This is just about what I'm tired to tell in the newsgroups. Take any question and analyse it namely as it is. Try to turn this toy, not confining yourself to the edges given by conventional conceptions. Try to get to know, what will occur if you change the conditions of experiment. Your eyes will get open. In order to advance more fruitfully in understanding, we need a funded project. This is not a request, and I don't mean a least to insist, only I already told you this simple thing and now recall by the way. Then you could not solve the problem and now you cannot comprehend the input to this labyrinth that leads just to the problem which you did not solve. These are all features. In reality this all is very simple. ;-) Kind regards, Sergey. |
