magnetic susceptibility

noun, Electricity
1.
the coefficient or set of coefficients of the magnetic intensity in any expression giving the components of magnetization as linear combinations of the components of magnetic intensity.
Also called susceptibility.
Encyclopedia Article for magnetic susceptibility

quantitative measure of the extent to which a material may be magnetized in relation to a given applied magnetic field. The magnetic susceptibility of a material, commonly symbolized by chim, is equal to the ratio of the magnetization M within the material to the applied magnetic field strength H, or chim = M/H. This ratio, strictly speaking, is the volume susceptibility, because magnetization essentially involves a certain measure of magnetism (dipole moment) per unit volume
