A coil of cross-sectional area .004m^2 consisits of 100 turns and has a resistnace of 4.5ohms. It rotates at 120rpm with its axis perpendicular to the external magnetic field of B=0.04T. At time, t=0s, the plane of the coil is parallel to the magntic field.
Find:
a) The maximum induced emf generated
b) The maximum magnetic torque on the coil.
