Demonstrating Paramagnetism Using Liquid Nitrogen.
Simmonds, Ray; And Others
Physics Teacher, v32 n6 p374-375 Sep 1994
Describes how liquid nitrogen is attracted to the poles of neodymium magnets. Nitrogen is not paramagnetic, so the attraction suggests that the liquid nitrogen contains a small amount of oxygen, which causes the paramagnetism. (MVL)
