* NdFeB magnet

CATEGORY 1

Applications that make use of the tractive and/or repelling force of the magnet, i.e., the attraction between a magnet and a soft magnetic material, such as a piece of iron or steel, or the attraction or repulsion between two magnets, is used to do mechanical work. The following applications are in this category:
 
  • Magnetic separators, magnetic holding devices, such as magnetic latches.
  • Magnetic torque drives
  • Magnetic bearing devices
CATEGORY 2

Applications that make use of the magnetic field of the magnet to convert mechanical energy to electrical energy. Some of these applications are:
 
  • Magnetos
  • Generators and alternators
  • Eddy current brakes (used widely for watt-hour meter damping). (This application could be listed under electrical to mechanical energy conversion; but as mechanical energy is used to create the eddy currents, it will be discussed with this group.)
CATEGORY 3

Applications that make use of the magnetic field of the magnet to convert electrical energy to mechanical energy. Some of these applications are:
 
  • Motors
  • Meters
  • Loudspeakers
  • Relays
  • Actuators, linear, and rotational
CATEGORY 4

Applications that use the magnetic field of the magnet to direct, shape and control electron or ion beams. Some of these applications follow:
 
  • Magnetic focused cathode-ray tubes
  • Traveling Wave Tubes
  • Magnetrons, BWO, Klystrons
  • Ion Pumps
  • Cyclotrons
