Acoil is wrapped with 300 turns of wire on the perimeter of a square frame (side length = 20 cm). each turn has the same area as the frame, and the total resistance of the coil is 1.5 ω. a uniform magnetic field perpendicular to the plane of the coil changes in magnitude at a constant rate from 0.50 t to 0.90 t in 2.0 s. what is the magnitude of the induced emf in the coil while the field is changing?
