A hollow cylindrical (inner radius = 1.0 mm, outer radius = 3.0 mm) conductor carries a current of 80 A parallel to its axis. This current is uniformly distributed over a cross section of the conductor. Determine the magnitude of the magnetic field at a point that is 2.0 mm from the axis of the conductor.
 a. 8.0 mT
  b. 3.0 mT
  c. 5.3 mT
  d. 16 mT
  e. 1.2 mT
