Vedclass · Answer

(B) The magnetic field at the center of a circular loop of radius $R$ carrying current $I$ is given by $B = \frac{\mu_0 I}{2R}$.From this,we can express the current $I$ as $I = \frac{2BR}{\mu_0}$.The magnetic moment $M$ of a current loop is given by $M = I A$,where $A = \pi R^2$ is the area of the loop.Substituting the value of $I$ into the formula for $M$,we get $M = \left( \frac{2BR}{\mu_0} ight) 	imes (\pi R^2)$.Simplifying this,we obtain $M = \frac{2 \pi B R^3}{\mu_0}$.
