Sorry, no etymologies found.
Fortunately, diamagnetism is too weak to cause shipwreck in this way.
Professor Main, head of physics at the University of Nottingham, worked on a project to levitate a frog using an effect called diamagnetism: ‘By changing the energy of electrons whizzing around in the nuclei of atoms, you create a force that acts on a molecular level.
In science, I would ask, is "diamagnetism" correctly explained by terming it "the property of any substance whereby it turns itself, when freely suspended, at right angles to the magnetic meridian."
Faraday didn't call for a vote when he developed the laws of electrolysis or discovered diamagnetism.
And, moreover, they have the power of exciting fresh whirls in neighboring conductors, and of repelling them according to the laws of diamagnetism.
In this way Professor Bjerknes has been able to reproduce analogues of all the phenomena of magnetism and diamagnetism, those phenomena which may be classed as effects of induction being directly reproduced, while those which may be classed as effects of mechanical action, and resulting in change of place, are analogous inversely.
If we present to it the vibrating body, it will be repelled, and we shall obtain the results known by the name of diamagnetism.
If the body is more sensitive than the air, there is direct magnetism, but if it is less so, there is diamagnetism.
And the results support the theories which attribute magnetism and diamagnetism to causes of a different nature.
In his well known theory of magnetism P. Langevin, in 1905, took into account the Curie law and arrived again, theoretically, at the difference between the origins of diamagnetism and paramagnetism.
