Vedclass · Answer

(D) The $B-H$ hysteresis loop represents the relationship between magnetic flux density $(B)$ and magnetic field intensity $(H)$ for a ferromagnetic material.When a ferromagnetic material is subjected to a cycle of magnetization,the work done per unit volume in one complete cycle is given by the integral $\oint H \cdot dB$.This integral is equivalent to the area enclosed by the $B-H$ hysteresis loop.Since this work done is converted into heat within the material,the area of the loop directly represents the energy dissipated as heat per unit volume per cycle of magnetization.
