RS Electrogravitic References: Part 7 of 19.

When individual molecules are not permanently magnetized, it is possible in 
some cases to have a relative magnetic permeability u which is less than one. 
Such a material, like hydrogen or BISMUTH, is called diamagnetic. It tends to 
expel magnetic field, and is repelled from regions of stronger magnetic field. 
The names paramagnetic and diamagnetic are sometimes confused: paramagnetic is 
analogous to a dielectric in an electric field, while diamagnetic is quite the 
opposite.

It is not possible to give a simple argument of why diamagnetism can occur. it 
is strictly speaking a quantum effect. However, one can see that there might 
be diamagnetic tendencies if electric currents can flow within molecules. An 
increasing magnetic field always tends to induce currents to flow in such a 
way as to tend to prevent the increase in the field. This is (at least 
temporarily) a diamagnetic kind of effect.

Thus the case where the relative magnetic permeablility u
