Classical theory of diamagnetism

Diamagnetic materials are substances that are weakly repelled by magnetic fields. This property is exhibited by substances that possess zero unpaired electrons. These materials get weakly magnetized in the direction opposite to that of the applied magnetic field. Some examples of diamagnetic materials are silver, … See more In 1845, Michael Faraday made the discovery of diamagnetism. To understand diamagnetism, first, we need to understand what diamagnetic materials are: Diamagnetic materials are substances that are weakly … See more Diamagnetism is used for the following purposes: 1.

Diamagnetism - Wikipedia

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… WebMay 11, 2024 · Langevin’s Theory of Paramagnetism The potential energy of the magnetic dipole in the external field is given by U = −→µB. −→ B (1) U = −µBB cos θ (2) According to Maxwell-Boltzmann statistics, at an absolute temperature T, the num- ber of magnetic dipoles having energy U is proportional to exp −U kBT .
