content: Replica of Faraday's 1821 experiment showing a free, current-carrying conductor will rotate about a bar magnet.
label: Description (Brief)
content: The experiments of Oersted and Ampere showed that an electric current would produce motion, but it lasted only until the magnet was perpendicular to the wire. In 1821, Michael Faraday of England showed how continuous motion could he produced from the combination of an electric current and a magnet. Faraday found that when a wire placed parallel to a magnet is freely suspended, a flow of current through it will produce a magnetic field which forces the wire to revolve around the magnet.
