In contrast, paramagnetic and ferromagnetic materials are attracted by a magnetic field . "'Diamagnetism "'is a quantum mechanical effect that occurs in all materials; when it is the only contribution to the magnetism the material is called diamagnetic.

Thus, a non-intuitive ( e . g ., a higher-energy for at least one species ) distribution of electrons in the combination of iron and oxygen must exist, in order to explain the observed diamagnetism and no unpaired electrons.

The " singlet state ", i . e . the " sign, means : the spins are " antiparallel ", i . e . for the solid we have antiferromagnetism, and for two-atomic molecules one has diamagnetism.

Earnshaw's theorem has even been proven for the general case of extended bodies, and this is so even if they are flexible and conducting, provided they are not diamagnetic, as diamagnetism constitutes a ( small ) repulsive force, but no attraction.
46.
The significance of this discovery is that classical physics does not allow for such things as paramagnetism, diamagnetism and ferromagnetism and thus quantum physics are needed to explain the magnetic events . may have contributed to Bohr's development of a quasi-classical theory of the hydrogen atom in 1913.

The Meissner effect is sometimes confused with the kind of diamagnetism one would expect in a perfect electrical conductor : according to Lenz's law, when a " changing " magnetic field is applied to a conductor, it will induce an electric current in the conductor that creates an opposing magnetic field.

This is what our article on Faraday says-" In 1845, he discovered the phenomenon that he named diamagnetism, and what is now called the Faraday effect : The plane of polarization of linearly polarized light propagated through a material medium can be rotated by the application of an external magnetic field aligned in the propagation direction.
