When a ferromagnetic material goes through a hysteresis loop, the magnetic susceptibility

When a ferromagnetic material goes through a hysteresis loop, its theremal energy is increased. Where does this energy come from?

Explain hysteresis loop

The relative permeability of a ferromagnetic material is 500 what is its magnetic susceptibility

Ferromagnetic material and non-magnetic material

For dimgnetic materials magnetic susceptibility is
