A coil is wrapped with 226 turns of wire on the perimeter of a circular frame (of radius 70 cm). Each turn has the same area, equal to that of the frame. A uniform magnetic field is directed perpendicular to the plane of the coil. This field changes at a constant rate from 22 mT to 61 mT in 79 ms. What is the magnitude of the induced average E in the coil, over the time interval 79 ms during which the field changes? Answer in units of V.
