An electric generator or electric motor consists of a rotor spinning in a magnetic field. The magnetic field may be produced by permanent magnets or by field coils. In the case of a machine with field coils, a current must flow in the coils to generate the field, otherwise no power is transferred to or from the rotor. The … See more For a machine using field coils, as is the case in most large generators, the field must be established by a current in order for the generator to produce electricity.
