1. Current flowing through the field coils:
a. Magnetizes the pole pieces
b. Makes the generator armature turn
c. Has no effect on the generator's magnetic field
2. The process of magnetizing the pole pieces involves:
a. Passing a magnetic field through them without change
b. Lining up the internal magnets of the pole oieces
c. Trying to get the tiny internal magnets of the pole pieces into random, helter-skelter positions so their fields cancel
