Thanks for the response. I think I understand the physical concepts but I'm still curious about how conductivity works in permanent magnets, and if a conducting magnet is useful as either a conductor or magnet.

The basic set up for a homopolar generator has a stationary magnet and a rotating conducting plate with contacts at the center and rim of the plate. I would think that even if magnet were spinning along the same axis, the magnetic field would not materially change and so the resulting current...
