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 B is given by T= D (4i - 3j), where D is a positive constant, and for this orientation of the loop the magnetic potential energy U = - µ· B is negative. The magnitude of the magnetic field is Bo = 13D/IA.
(a) Determine the vector magnetic moment of the current loop.
(b) Determine the components Bx, By, and Bz of B.
