A loop of radius r = 3.0 cm is placed parallel to the xy-plane in a uniform magnetic field = 0.75 T . The resistance of the loop is 18 .
 
  Starting at t = 0, the magnitude of the field decreases uniformly to zero in 0.15 seconds. What is the magnitude of the electric current produced in the loop during that time?
  A) 0.79 mA
  B) 3.9 mA
  C) 1.7 mA
  D) 2.1 mA
  E) 0.20 mA
