[SOLVED] Rotating Magnet
I had forgotten about a web page I made several months ago. It's regarding a rotating magnet. There are some cool physics in this page so take a look
www.geocities.com/physics_world/em/rotating_magnet.htm
Back in the early 60's Edward Purcell came out with an idea of how to look at the relativity of electric fields in terms of charge densities. It's not a widely know fact but under some circumstances you can have a zero charge density in one frame of referance and a non-zero charge density in another. If you want to go into the excrutiaing detail the see also
