Students explore the relationship between electricity and magnetism. They test the strength of different electromagnets and construct and operate a DC motor. They construct a galvanometer and use a permanent magnet and a solenoid to induce a current. They explore producing an electric generator and learn the difference between AC and DC. Maxwell and his discovery that all electromagnetic waves travel at the speed of light is discussed.
