Faraday Motor demonstration Posted by: youtuuba
Video duration: 99 seconds In the early 1800s, physicist Michael Faraday invented the first device to convert electrical energy into mechanical motion. This is an easily built version of his motor. The magnet sets up a magnetic field, and the electrical current through the screw sets up a separate electromagnetic field around the screw. The two fields react and the result is rotation.
