Generators and Motors
We see the relationship between electricity and magnetism in action as we learn about generators and motors at the Georgia Racing Hall of Fame.

Vocabulary
alternating current - current that reverses direction multiple times per second. commutation - the electromechanical process by which direct current is turned into alternating current. direct current - current that runs in only one direction. electromagnetic induction - a phenomenon that creates a current in a circuit when there is relative motion between the wire and the magnetic field. Faraday’s Law - a law that predicts how a magnetic field will interact with an electric circuit to produce an electromotive force. generators - devices that convert mechanical energy into electrical energy. motors - devices that convert electrical energy into mechanical energy. rotor - a moving component of an electromagnetic system in an electric motor or generator. Its rotation is due to the interaction between the windings and magnetic fields which produces a torque around the rotor's axis. stator - the stationary component of an electric motor or generator.
