A Coil Is Wrapped with 300 Turns of Wire on the Perimeter

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 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?

A) 2.4 V
B) 1.6 V
C) 3.2 V
D) 4.0 V
E) 8.4 V
