A  coil is wrapped with 300 turns of wire on the perimeter of a circular frame (radius = 8.0 cm).  Each turn has the same area, equal to that of the frame. A uniform magnetic field is turned on  perpendicular to the plane of the coil. This field changes at a constant rate from 20 to 80 mT in a  time of 20 ms. What is the magnitude of the induced emf in the coil at the instant the magnetic  field has a magnitude of 50 mT?
