A rectangular coil of 70 turns, dimensions 0.100 m by 0.200 m and total resistance 10.0 ohms, rotates with angular speed 32.0 rad/s about the y axis in a region where a 1.00 T magnetic field is directed along the x axis. The rotation is initiated so that the plane of the coil is perpendicular to the direction of vector B at t = 0.

(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 = 0.0500 s.

_______V

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

_______N·m
