A cоil is wrаpped with 250 turns оf wire оn the perimeter of а squаre frame (side length = 15 cm). Each turn has the same area as the frame, and the total resistance of the coil is 3.0 Ω. A uniform magnetic field perpendicular to the plane of the coil, changes in magnitude at a constant rate from 0.4 T to 0.9 T in 2.0 seconds. What is the magnitude of the induced emf in the coil while the field is changing?
