Making Magnets  









Types of Magnets
  





Hitting a Magnet
  • If a magnet is hit hard, its domains can be knocked out of alignment.















Heating a Magnet
  • Heating a magnet will also destroy its magnetism.
  • Above a certain temperature, every ferromagnetic material loses its magnetic properties.
 





Breaking a Magnet
  • If a magnet is broken in two, the result is two smaller magnets.
  • Each smaller magnet has its own north pole and south pole.
