There is a close relationship between magnetic forces and the generation of electric current. Explain how magnets can be used to generate electric current and how electric current can be used to create electromagnets. For each, give an example of a device you would find around the home.

Inside a generator is a magnet, some electrical wire, and a source of mechanical energy. The mechanical energy moves the wire into the magnetic field of the magnet so that the wire cuts through the magnetic lines of force. As a result, electric current is produced. Electric generators can come in all sizes
