Electric Current And Magnetism
A magnetic field is created in space whenever a current flows through a conductor. This magnetic field will exert a force on the magnetic field of other nearby current-carrying conductors. This is the principle behind the design of an electric motor.
An electrical generator operates on a principle similar to an electric motor. In a generator, mechanical energy forces a conductor to move through a magnetic field. The magnetic field forces the electrons in the conductor to move, which causes an electric current.
