Vedclass · Answer

(B) The relationship between magnetic flux density $B$ and magnetic field intensity $H$ is given by $B = \mu_0 \mu_r H$.From this,the relative permeability $\mu_r$ is proportional to the ratio $\frac{B}{H}$,which represents the slope of the $B-H$ curve at any given point.$\mu_r \propto \frac{B}{H} = 	ext{slope of } B-H 	ext{ curve}$.To find the highest relative permeability,we need to identify the point on the curve where the slope is maximum.By observing the given $B-H$ graph,the curve is steepest in the region around point $Q$. Therefore,the slope is highest at point $Q$.

The basic magnetization curve for a ferromagnetic material is shown in the figure. Then,the value of relative permeability is highest for the point
