Paramagnetism and Diamagnetism – 5G30.00

Para/Diamagnetism of Several Samples – 5G30.10


  • Place pivot base and place the swing arm over the bearing.
  • Place two samples on the pivot arm- bismuth, water, or cupric sulfate.
  • Hold magnet very close to the sample but not touching it.
  • There will be an attraction of cupric sulfate and a repulsion of water or bismuth.

Paramagnetism of Liquid Oxygen – 5G30.20

Param. Liq. O2_5g30.20

  • A metal cone is partially filled with liquid nitrogen and placed over the parallel pole faces of a strong magnet.
  • Liquid oxygen collects at the point of the cone and drips between the pole faces.
  • The liquid is attracted to the closest pole face and eventually bridges the gap between the faces.
  • This demo is small, so a camera is used to display it.
