magnetic field
magnetic poles
spread out from one pole and curve around to the other
attract each other
using a stronger ferromagnetic material for the core
alternating current transmitted at high voltages, but usually used at low voltages.
In an electric motor, the armature spins continuously.
Electric current from a generating plant is
