The rotor in a certain electric motor is a flat, rectangular coil with 79 turns of wire and dimensions 2.61 cm by 3.80 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 11.0 mA. In this orientation, the magnetic moment of the rotor is directed opposite the magnetic field. The rotor then turns through one-half revolution. This process is repeated to cause the rotor to turn steadily at an angular speed of 3.48 103 rev/min. (a) Find the maximum torque acting on the rotor.
