Physics

The rotor in a certain electric motor is a flat, rectangularcoil with 89 turns of wire and dimensions 2.57 cm by 4.20 cm. Therotor rotates in a uniform magnetic field of 0.800 T. When theplane of the rotor is perpendicular to the direction of themagnetic field, the rotor carries a current of 10.6 mA. In thisorientation, the magnetic moment of the rotor is directed oppositethe magnetic field. The rotor then turns through one-halfrevolution. This process is repeated to cause the rotor to turnsteadily at an angular speed of 3.72 103 rev/min.
(a) Find the maximum torque acting on the rotor.
