• A magnetic field is an area where the forces of
  attraction from a magnet are working.
• An electromagnetic field has the same effect as a
  magnetic field but it can be turned on and off by
  stopping the electricity which it requires.
• Electric motors are one of the main uses of
  electromagnetic fields.
• Electric motors convert electrical energy into
  mechanical energy. The mechanical energy is
  normally used to turn things like wheels.
• A generator is like an electric motor used the
  other way where mechanical energy is converted
  to electrical energy.
• Other uses of electromagnetic fields are LCD
  screens and electromagnetic cranes.
