An electric generator contains a coil of 100 turns of wire, each forming a rectangular loop 50.0 cm by 30.0 cm. The coil is placed entirely in a uniform magnetic field with magnitude B = 3.50 T and initially perpendicular to the coil's plane. The coil is rotated with an angular speed of 100 rev/min about an axis perpendicular to B. The total resistance is 100 N. What is the magnetic torque acting on the coil when the induced emf is zero. %3D
