In the presence of an external magnetic field, a ferromagnetic substance1 exhibits a behavior that is quite different from the behavior of a paramagnetic body. Under the same conditions, the former shows an induced magnetization that is much greater than the corresponding magnetization exhibited by the the latter. Moreover, the functional relation between the magnetic field and the magnetization is nonlinear in a ferromagnetic body and linear in a paramagnetic one. Finally, in a ferromagnetic body the magnetization depends not only on the actual value of the magnetic field but its history (i.e., hysteresis).
