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

    A) P

    B) Q    

    C) R   

    D) S

    Correct Answer: B

    Solution :

    [b] \[B={{\mu }_{0}}{{\mu }_{r}}H\Rightarrow {{\mu }_{r}}\propto \frac{B}{H}\]= slope of B-H curve According to the given graph, slope of the graph is highest at point Q.
