Acoil is wrapped with 238 turns of wire on the perimeter of a square frame of sides 17.7cm. each turn has the same area, equal to that of the frame, and the total resistance of the coil is 1.39ohms. a uniform magnetic field is turned on perpendicular to the plane of the coil. if the field changes linearly from 0 to 0.455wb/m^2 in a time of 1.06s find the magnitude of the induced emf in the coil while the field is changing. answer is units of v.
