Vedclass · Answer

(C) The hysteresis loop represents the relationship between magnetic field $(B)$ and magnetic intensity $(H)$ for a ferromagnetic material. Coercivity is defined as the value of the reverse magnetic intensity $(H)$ required to reduce the residual magnetism $(B)$ to zero. In the given hysteresis loop,the point $R$ lies on the negative $H$-axis where the magnetic field $B$ is zero. Therefore,the point $R$ represents the coercivity of the material.

If the given figure shows the relation between magnetic field ($B$ - along $y$-axis) and magnetic intensity ($H$ - along $x$-axis) of a ferromagnetic material,then the point that represents the coercivity of the material is
