A 200-loop coil of cross sectional area 8.5 lies in the plane of the paper. Directed out of the plane of the paper is a magnetic field of 0.06 T. The field out of the paper decreases to 0.02 T in 12 milliseconds.

Question

A 200-loop coil of cross sectional area 8.5   lies in the plane of the paper. Directed out of the plane of the paper is a magnetic field of 0.06 T. The field out of the paper decreases to 0.02 T in 12 milliseconds.

(a) What is the magnitude of the change in magnetic flux enclosed by the coil?
