Multiple Choice
A coil 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 .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?
A) 2.4 V
B) 1.6 V
C) 3.2 V
D) 4.0 V
E) 8.4 V
