A circular loop of wire with area A lies in the xy-plane. As viewed along the z-axis looking in the -z direction toward the origin, a current I is circulating clockwise around the loop. The torque produced by an external magnetic field is torque = D[5i,-3j] where D is a positive constant, and for this orientation of the loop the magnetic potential energy U = -mu cross B is negative. The magnitude of the magnetic field is 14D/IA
