A 200-loop coil of cross sectional area 8.5 cm² lies in the plane of the page. An external magnetic field of 0.060 T is directed out of the plane of the page. The external field decreases to 0.020 T in 12 milliseconds.

(a) What is the magnitude of the change in the external magnetic flux enclosed by the coil? ____ T*m^2
(b) What is the magnitude of the average voltage induced in the coil as the external flux is changing?  ____V
(c) if the coil has a resistance of 4.0 ohms, what is the magnitude of the average current in the coil? _____A
