Consider an ideal magnet with even field across its pole's surface and a block of iron over it (fig B). (Disregard the "moving coil" for now)
The question is: Is the magnetic field between the iron block and magnet any different than elsewhere across the magnet's pole?
In other words:
From what I understand, if you move a coil through a uniform magnetic field (Fig A) (not in and out of the field), the coil does not produce any electricity. (Am I right?)
Would the coil produce electricity in (Fig B) if moved under the iron block and away from the block?
