So the electric and magnetic fields are linked, when they're at 90 degrees and self propagating they're a photon. I sort of know you can have TE and TM propagation. But I'm having trouble seeing how the electric field link is maintained with magnetism; can someone explain to me where the electric filed is in a magnet? For instance, say you have either a permanent magnet, or a magnet caused by moving electric charge. Say it was just a rectangle, with magnetic flux inside it, either changing flux or stationary, I don't care. Where is the respective linked electric field? Please feel free to sketch any pictures for a simple explanation, I'm not fussy about quality. Thanks!
