magnetic susceptibility(Noun)

a measure of the magnetization of a material per unit of applied magnetic field

Magnetic Susceptibility

The specific intrinsic susceptibility of any material for magnetic induction. It refers to the particle of matter, and not to the mass, as in the latter its own particles react on each other and bring about what is termed permeability, q. v. (See also Magnetization, Coefficient of Induced, and Magnetic Induction, Coefficient of.) Synonym--Coefficient of Induced Magnetization.
