J7-12: CURIE POINT OF IRON

j7-12aj7-12b

Additional Info

  • ID Code: J7-12
  • Purpose: Show the Curie point of iron.
  • Description: An iron wire is normally ferromagnetic, and therefore strongly attracted to the magnet as shown in the photograph. When heated so that it glows red hot by passing an electric current through it, the iron rises above its Curie point and loses its ferromagnetism, so springs at either end of the wire pull it away from the magnet.
