A long hollow cylindrical conductor (inner radius = 2.0 mm, outer radius = 4.0 mm) carries a current of 12 A distributed uniformly across its cross section. A long wire which is coaxial with the cylinder carries an equal current in the same direction. What is the magnitude of the magnetic field 3.0 mm from the axis?
 a. 1.1 mT
  b. 1.4 mT
  c. 1.7 mT
  d. 2.0 mT
  e. 0.2 mT

 a. 0.82 mT
  b. 0.93 mT
  c. 0.70 mT
