Question 2

A 5-turn square loop (10 cm along a side, resistance = 4.0 ) is placed in a magnetic field that makes an angle of 30 with the plane of the loop. The magnitude of this field varies with time according to B = 0.50t2, where t is measured in s and B in T. What is the induced current in the coil at t = 4.0 s?
 a. 25 mA
  b. 5.0 mA
  c. 13 mA
  d. 43 mA
  e. 50 mA
