A 200-loop coil of cross sectional area 8.5 cm2 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? (b) What is the average voltage induced in the coil as the flux is changing? (c) If the coil has a resistance of 4.0 ohms, what is the magnitude of the current in the coil?
