Faraday’s answer turned out to be one of the most useful discoveries in the history of science. In 1831 Faraday made a circuit with a coil of wire. In the circuit was a galvanometer, which is an instrument that measures small amounts of electric current. Faraday then put a magnet inside the coil of wire. He discovered that a current was created in the wire whenever the magnet was moved in or out of the coil. When the magnet was just sitting still, no electricity flowed. From this experiment came what is known as Faraday’s law: A moving magnetic field creates an electric current in a wire.
Using Ørsted’s discovery, the first electromagnet and the first electric motor were both built by 1823. The English scientist Michael Faraday made the next major contribution to the understanding of electricity and magnets. Faraday was a brilliant experimenter. He knew from Ørsted’s experiment that a moving current could create magnetic force. He wondered if the opposite was also true. Could a magnet cause an electric current to flow in a wire? Faraday’s answer turned out to be one of the most useful discoveries in the history of science.
