2016-1-1  Thus κ or μ indicates a property of a mineral where the electrons in the crystal are polarized to produce magnetism. Sometimes, κ is expressed in terms of electronic structure. It is then known as molar susceptibility, κM. Magnetic susceptibility is a measure of dipole orientation and is a function of the frequency of the source.
