The rotor in a certain electric motor is a flat, rectangular coil with 89 turns of wire and dimensions 2.41 cm by 4.04 cm. The rotor rotates in a uniform magnetic field of 0.800 T. When the plane of the rotor is perpendicular to the direction of the magnetic field, the rotor carries a current of 10.9 mA. In this orientation, the magnetic moment of the rotor is directed opposite the magnetic field. The rotor then turns through one-half revolution....
