A loop carrying current I lies in the x–y plane as shown in the figure. The unit vector ˆk is coming out of the plane of the paper. The magnetic moment of the current loop is : Image related to
\[a^{2}I\hat{k}\]
\[\left( \frac{\pi}{2}+1 \right)a^{2}I\hat{k}\]
\[-\left( \frac{\pi}{2}+1 \right)a^{2}I\hat{k}\]
\[\left( 2\pi+1 \right)a^{2}I\hat{k}\]
