J7-11: PARAMAGNETISM AND DIAMAGNETISM

PURPOSE: To demonstrate paramagnetic and diamagnetic materials.

DESCRIPTION: A sample of copper sulfate, a paramagnetic material, is slightly attracted to a magnet. A sample of bismuth, a diamagnetic material, is slightly repelled by a magnet. Samples of copper sulfate and bismuth are balanced on a light dowel rod hanging by a strip of plastic audio recording tape. The 2-kilogauss horseshoe magnet is used to push and/or pull the samples around, illustrating the small paramagnetic and diamagnetic forces.

SUGGESTIONS:

REFERENCES: (PIRA 5G30.25)

EQUIPMENT: Suspended samples of bismuth and copper sulfate on stand with horseshoe magnet.

SETUP TIME: 5 min.
