Vedclass · Answer

(B) $1$. Retentivity is the value of magnetic induction $B$ when the magnetizing field $H$ is zero. From the graph,at $H = 0$,$B = 1.0 \; T$.$2$. Coercivity is the value of the reverse magnetizing field $H$ required to reduce the magnetic induction $B$ to zero. From the graph,at $B = 0$,$H = -50 \; A/m$. The magnitude of coercivity is $50 \; A/m$.$3$. Saturation magnetization is the maximum value of magnetic induction $B$ reached by the material. From the graph,the maximum value of $B$ is $1.5 \; T$.Therefore,the retentivity,coercivity,and saturation are $1.0 \; T, 50 \; A/m$ and $1.5 \; T$,respectively.

The figure shows the experimentally measured $B$ vs. $H$ variation in a ferromagnetic material. The retentivity,coercivity,and saturation of the material are,respectively:
