1821: First Electric Motor
Innovation: First Electric Motor
By: Michael Faraday
An electric motor is simply a device that makes mechanical energy from electrical energy. The first person to create an electric motor was Michael Faraday in 1821. Faraday’s motor was designed so that two cups filled with mercury would contain a magnet and a wire with one being fixed and the other free to move. Whenever a current was passed through the wire, the free moving magnet or wire would revolve around its fixed partner due to the electromagnet forces being produced. Faraday’s motor proved that motion could be created by electricity and stimulated a world of research into electromagnetism. This motor led to the design of the advanced motors seen in the electric tools used in the construction field today.
