context_page_description: An electric motor changes electrical energy into mechanical movement. A dynamo or an electric generator does the reverse: it changes mechanical movement into electric energy. Most electric motors work by using the force of magnetism. Electrostatic motors have also been used.
  Machines using electric motors include: fans, washing machines, fridges, pumps, and vacuum cleaners.
