GENERATORS AND TRANSFORMERS
... An electric generator consists of a magnet, which creates a magnetic field, and a loop of wire which rotates in the magnetic field. As the wire rotates in the magnetic field, the changing strength of the magnetic field through the wire produces a force which drives the electric charges around the w ...
