Clarification needed regarding the Magnetization and Demagnetization process happened in the Hysteresis loop?

Ans) In classical electromagnetism or magnetic polarization is the vector field that expresses the density of permanent or induced magnetic dipole moments in a magnetic material. The origin of the magnetic moments answerable for magnetization can be either microscopic electric currents resulting from the motion of electrons in atoms, or the spin of the electrons or the nuclei. Net magnetization results from the response of a material to an external magnetic field, together with any unbalanced magnetic dipole moments that may be inherent in the material itself; for instance, in ferromagnets. Magnetization is not always homogeneous within a body, but rather varies among different points. Magnetization also defines how a material responds to an applied magnetic field as well as the way the material changes the magnetic field, and can be used to measure  the forces that result from those interactions. It can be compared to electric polarization, which is the measure of the corresponding response of a material to an electric field in electrostatics. Physicists and engineers describes magnetization as the quantity of magnetic moment per unit volume. It is represented by a vector M.
