Michael Faraday (22 September 1791 – 25 August 1867) was an English physicist and chemist. In 1821, soon after Oersted's discovery, he published his work on—what he called—electromagnetic rotation (the principle behind the electric motor). In 1831, Faraday discovered electromagnetic induction, the principle behind the electric transformer and electric generator. In chemistry Faraday discovered benzene, contributed importantly to electrochemistry, and popularized terminology such as anode, cathode, electrode, and ion.
