A coil is wrapped with 350 turns of wire on the perimeter of a circular frame (radius = 4.4 cm). Each turn has the same area, equal to that of the frame. A uniform magnetic field is applied perpendicular to the plane of the coil. This field changes at a constant rate from 1.4 to -5.3 mT in a time of 7.5 ms. What is the magnitude of the induced emf in the coil at the instant when the magnetic field has a magnitude of -1.95 mT
