Diamagnetism describes how a material reacts when plunged into a magnetic field. Paramagnetism says almost the same thing. The difference between para- and dia-magnetism is just the sign of the response of the material with respect to the magnetic field.

Diamagnetism of Metals

The electrons in a material generally settle in orbitals, with effectively zero resistance and act like current loops. Thus it might be imagined that diamagnetism effects in general would be common, since any applied magnetic field would generate currents in these loops that would oppose the change, in a similar way to superconductors, which are essentially perfect diamagnets. However, since the electrons are rigidly held in orbitals by the charge of the protons and are further constr… WebAug 6, 2010 · The Bohr-van Leeuwen theorem is often summarized as saying that there is no classical magnetic susceptibility, in particular no diamagnetism.
