Arectangular coil of 65 turns, dimensions 0.100 m by 0.200 m, and total resistance 10.0 ? rotates with angular speed 29.5 rad/s about the y axis in a region where a 1.00-t magnetic field is directed along the x axis. the time t = 0 is chosen to be at an instant when the plane of the coil is perpendicular to the direction of b with arrow.

(a) calculate the maximum induced emf in the coil.
v

(b) calculate the maximum rate of change of magnetic flux through the coil.
wb/s

(c) calculate the induced emf at t = 0.050 0 s.
v

(d) calculate the torque exerted by the magnetic field on the coil at the instant when the emf is a maximum.
