Vedclass · Answer

(A) Magnetic susceptibility $(\chi)$ is a measure of how easily a substance can be magnetized in an external magnetic field.For ferromagnetic substances,the atoms possess a permanent magnetic dipole moment,and they align strongly in the direction of the external magnetic field.Due to this strong alignment,ferromagnetic materials exhibit a very large and positive magnetic susceptibility.Therefore,for a ferromagnetic substance,$\chi >> 1$.

The magnetic susceptibility of a ferromagnetic substance is
