A square loop is free to rotate around the axis, as shown in figure. The current / is directed in the direction of z on the fixed size. The loop is rotating around the = axis. If the plane of the loop is making angle o with the xz plane, and magnetic flux B is: B=a+a, Find angle & such that torque is equal to zero. x a I 690 x A square loop is free to rotate around the axis, as shown in figure.
