A rigid circular loop has a radius of 0.20 m and is in the xy-plane. A clockwise current I is carried
by the loop, as shown. The magnitude of the magnetic moment of the loop is 0.75 A · m2. A
uniform external magnetic field, B = 0.20 T in the positive x-direction, is present. An external
torque changes the orientation of the loop from one of lowest potential energy to one of highest
potential energy. The work done by this external torque is closest to
