Example:
Water flows at 2 gallons/sec. Gallon say contains 1 million water molecules The area x length that contains the water is 1000m^2 x 100^m. Can you figure out how many water molecules there is, and what is their average velocity in m/sec.....Answer is yes. **********LIKEWISE************** Model: Current in a wire moving in between two N &S magnets I = amperes = coulombs/sec = n_I q/sec (n_I is the number of charges) A = area of wire L = length of wire F = ILB = n_I AL qv B Since the number of charges in L is n_I *A* L = "n" therefore F= nqv B where "n" is the total number of charges affected by the magnetic field B. ----------------------------------------------------- More precisely F= nqv B sin(angle) is the EXACT same as the Force applied on a single charge where n = 1 ( F_singlecharge = qv B sin(angle) ) In fact both the wire and the single charge also deflect in the same direction as pertaining to the right hand rule. CONCLUSION: THERE IS NO DIFFERENCE BETWEEN THE ****FORCE**** OF TWO N&S MAGNETS ON A SINGLE CHARGE OR ON THE CURRENT (MULTIPLE MOVING CHARGES) IN A WIRE. *********************************** The above is important because in the physics book that specifies the force is a result between the ****magnetic field of the current***** versus the magnetic field of the N&S magnets thus LIKEWISE for a single charge. And the Force for the current in that wire = nqv x B thus nqv DOES NOT MEAN the circular magnetic field doesn't interact with the N&S magnet's magnetic field. (F= g x m and not F= g x Gm/r^2 likewise for F = B x nqv) |

AND Speaking of idiots who can't read it was about a VECTOR cross- product related to ***Fleming's right hand rule*** to which Misses Erica Gisse ****WHO CANNOT READ AND ALWAYS COMPLAINS*** gave an Area of a parallelogram as a dumb answer. Actually it is better if Misses Erica Gisse keeps snipping everything and "only" complains, for if she gave any MORE details than that, then people might realize she ain't very bright. |

[...] You didn't understand the concept of what I wrote, nor did you point to what you believed to be incorrect. It seems you can't read a few paragraphs yet strangely enough you contiunously point people to a zillion lines of text. |
