How does the dynamo work?

The generator/dynamo is made up of stationary magnets (stator) which create a powerful magnetic field, and a rotating magnet (rotor) which distorts and cuts through the magnetic lines of flux of the stator. When the rotor cuts through lines of magnetic flux it makes electricity. read more

Artwork: A simple generator like this produces alternating current (an electric current that periodically reverses). Each side of the generator (green or orange) is either moving up or down. When it moves up, it will generate a current flowing one way; when it moves down, the current flows the other way. read more

Quick Answer. Dynamos produce electric current by rotating a wire within a magnetic field. Another method rotates a permanent magnet around coils of wire. read more
