A cod is wrapped with 400 turns of wire on the perimeter of a circular frame of radius 8.5cm 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 10.0 to 80.0mT in a time of 20.0ms What is the magnitude of the induced emf in the coil at the instant the magnetic field has a magnitude of 50.0mT?
