Far·a·day \ˈfar-ə-ˌdā\ , Michael (1791–1867), British physicist and chemist. Faraday ranks as one of the greatest experimental scientists of all time. In the field of electricity he demonstrated in 1821 that the force acting on a current-carrying wire in a magnetic field was circular and directed around the wire. In 1831 he discovered that an electromotive force can be induced in a circuit by varying the magnetic flux linked with the circuit, and he built an elementary electric motor and dynamo. Faraday also stated the basic laws of electrolysis and introduced the terms anode, cathode, anion, cation, and electrode.
