A long solenoid (n = 1 500 turns/m) has a cross-sectional area of 0.40 m2 and a current given by I = (4.0 + 3.0t2) A, where t is in seconds. A flat circular coil (N = 300 turns) with a cross-sectional area of 0.15 m2 is inside and coaxial with the solenoid. What is the magnitude of the emf induced in the coil at t = 2.0 s?
 a. 2.7 V
  b. 1.0 V
