by Carl Johnk, admittedly an older text, but then again I'm, pretty old:
Carl states that the magnetic moment in diamagnetic material is zero in absence of a magnetic field. Application of a magnetic field exerts a a force ( Lorentz force) on the orbiting electron which will generate a small magnetic field. "Diamagnetism is presumed to exist in all materials...."
Typical values are -0.95X10^-5 for copper, -.8X 10^-5 for germanium. Paramagnetic material has a much higher susceptibility: FeSO4, FeO3, magnetite and hematite being on the order of 10^-3. In both cases the net magnetism at rest with no magnetic field applied is Zero.
