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.
