Electricity explained How electricity is generated
An electric generator is a device that converts a form of energy into electricity. There are many different types of electricity generators. Most electricity generation is from generators that are based on scientist Michael Faraday's discovery in 1831. He found that moving a magnet inside a coil of wire makes (induces) an electric current flow through the wire.
