 ### 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 $\chi_m$, is equal to the ratio of the magnetization $M$ within the material to the applied magnetic field strength $H$, or $\chi_m=M/H$. This ratio, strictly speaking, is the volume susceptibility, because magnetization essentially involves a certain measure of magnetism (dipole moment) per unit volume.
