Harald Actually Harold, Maxwell actually first published this relationship a few years earlier than did Lorentz. I suspect that it predates even Maxwell, so perhaps someone else will research it's earliest origins and who actually deserves the credit for this rather useful observation. "Lorentz introduced this force in 1892.[5] However, the discovery of the Lorentz force was before Lorentz's time. In particular, it can be seen at equation (77) in Maxwell's 1861 paper On Physical Lines of Force. Later, Maxwell listed it as equation "D" of his 1864 paper, A Dynamical Theory of the Electromagnetic Field, as one of the eight original Maxwell's equations. Not my words, neither are they from a physics text, but from this source: http://en.wikipedia.org/wiki/Lorentz_force I like to give credit where credit is due, beside the the symbology of a vector math equation to usenet ASCII symbology tends to be a total waste of time. It's easier simply to point readers to the first equation listed under "History" in the cited link, which physicists will recognize as being essentially the same equation taught in 1st year physics as the Lorentz Force. (In actuality, Lorentz is best known for his classic method of establishing the value of an Ohm.) [See, Harnwell, "Principles of Electricity and Electromagnetism", McGraw Hill. 1949.] Where Maxwell obtained this little gem is to me interesting. Perhaps he was inspired by the observations of Faraday, who history tells us was a far better experimentalist than a gifted mathematician. Maxwell was a gifted mathematician, as well as a physicist of no trivial note. So to me, that explanation would make sense. Still, history becomes a bit cloudy in the days around 1890. So, I have to ask the question, whose earlier work predated that of Faraday, Maxwell, and Lorentz, since all three appear to share a common nexus??? Silly I know, but it's a question that fascinates me. Sort of a physics version of the "Cold Case Files." Have fun thinking about this one. Harry C. |

Harald Actually Harold, Maxwell actually first published this relationship a few years earlier than did Lorentz. Sorry about that! Anyway, my point was that Lorentz used it much (so that it even became known as the Lorentz force). I suspect that it predates even Maxwell, so perhaps someone else will research it's earliest origins and who actually deserves the credit for this rather useful observation. "Lorentz introduced this force in 1892.[5] However, the discovery of the Lorentz force was before Lorentz's time.

So, I have to ask the question, whose earlier work predated that of Faraday, Maxwell, and Lorentz, since all three appear to share a common nexus??? Hmm... it is said that it was really Faraday who lied the basis of it all. But I wasn't there. ;-) Silly I know, but it's a question that fascinates me. Sort of a physics version of the "Cold Case Files." Good one! Cheers, Harald |
