The most recent Fields & Energy post on Ampère’s Law represents a milestone in my development of how electricity and magnetism work. Up until this point, I’ve been presenting the historical foundations of physics in general and electromagnetism in particular as developed by other people: Newton, Coulomb, Ampère, Faraday, Ohm, Gauss, Maxwell, and all the rest. In the last post, however, I introduced a very fundamental concept that is original to me: the right-hand rule for radiation. At least, I think it’s my discovery. Unless John A. Wheeler knew it all along. I can’t be certain.
