-
And the the answer is, I think it's all to do with all these horrible things you learn about in magnetism, diamagnetism and paramagnetism.
-
The theorem fails because diamagnetism, a quantum phenomenon, cannot be approximated by any configuration of classical magnets, as considered in Earnshaw's theorem.

Topics included chemical physics, diamagnetism, and nuclear physics.

And the work that Tyndall did on diamagnetism is very accurate.
-
For example, in one chapter, diamagnetism is presented as an extension of atomic physics that explains spin and orbital moments.
Academic text (2003) -
In a subsequent chapter, paramagnetism is discussed as an effect that tends to overshadow diamagnetism.
Academic text (2003) -
Diamagnetism was discovered by Michael Faraday in 1846, but no one at the time thought that it could lead to any appreciable effects.
Academic text (1998) -
In 1933, the key discovery of perfect diamagnetism by Walter Meissner and R. Ochsenfeld in Berlin showed superconductivity to be a reversible thermodynamic phenomenon.
Academic text (1993) -
Owing to the readjustment of electron orbits in a magnetic field, all objects, even "nonmagnetic" ones, exhibit diamagnetism, which determines the lowest possible limit of their magnetic response.
Academic text (1998) -
The property of diamagnetism causes materials like copper to be slightly repelled by a magnet when exposed to a magnetic field.

Morphology
diamagnetism = diamagnetic (semi-transparent) = dia + magnet + dia + ism
Standard noun formation from the adjective 'diamagnetic' using '-ism' to denote the property or phenomenon.
Etymology
Diamagnetism comes from the parts dia- meaning 'across' or 'opposite' and magnet from a word for a 'stone that pulls iron'. So, diamagnetism is when a material is pushed slightly away from a magnet, which is why metals like copper are weakly repelled.
