Here is my misunderstanding , for the example let's ignore resistance losses , say i have a infinite length of coil , and an infinite strip of magnets passing through that coil, each magnet separated by some distance from the next one , the strip of magnets move through the middle of the coil , what kind of current I would get out of the coil , AC or DC?
I understand that when a magnet approaches a coil and goes past it it creates AC since the field gets stringer and then gradually decreases , but here the flux changes along the length of the coil but overall the magnet never approaches the coil itself nor leaves it.
a similar situation could be modeled by using a toroid coil and a strip of magnets rotating inside the coil.
