MAGNETIC SUSCEPTIBILITY - Texas A&M University

Physical Background. Magnetic susceptibility is the degree to which a material can be magnetized in an external magnetic field. If the ratio between the induced magnetization and the inducing field is expressed per unit volume, volume susceptibility (k) is defined ask = M/H,. where M is the volume magnetization induced in a material of susceptibility k by the applied external field H.
