A cоil is wrаpped with 200 turns оf wire оn the perimeter of а squаre frame (side length = 28 cm).  Each turn has the same area as the frame, and the total resistance of the coil is 4.0 Ω.  A uniform magnetic field perpendicular to the plane of the coil, changes in magnitude at a constant rate from 0.3 T to 0.8 T in 2 seconds.  What is the magnitude of the induced emf in the coil while the field is changing?
