A coil is wrapped with 647 turns of wire on the perimeter of a circular frame (of radius27 cm). Each turn has the same area, equal to that of the frame. A uniform magnetic field is directed perpendicular to the plane ofthe coil. This field changes at a constant rate from 22 mT to 62 mT in 67 ms. What is the magnitude of the induced E in the coil at the instant the magnetic field has a magnitude of 53 mT? Answer in units of V.
