A generator is a machine that converts mechanical energy into electrical energy. Originally called a dynamo, it makes use of the principle of electromagnetic induction, which was discovered in 1831 by the English physicist Michael Faraday. He reversed the work of Hans Christian Oersted (1777-1851), who had discovered that an electric current created a magnetic field. By Faraday's reasoning, it should be possible for a magnetic field to generate an electric current. (American inventor Joseph Henry came to the same conclusion independently.) Faraday took a coil of wire, attached it to a galvanometer and then inserted a magnet into the coil. As the magnet moved, its magnetic lines of force were cut by the coil and the galvanometer registered current. The same thing happened when the magnet was removed; electricity was induced to flow in the coil, although the flow was in the opposite direction. In fact, the results...
