A coaxial cable consists of a solid inner cylindrical conductor of radius 1.00 mm and an outer conductive cylindrical shell of inner radius 2.00 mm and outer radius 3.00 mm concentric with the inner conductor. There is a current of 18.0 A down the inner conductor and an equal return current in the outer conductor. The current density is uniform over each conductor. What is the magnitude of the magnetic field at a distance from the center of the inner conductor at (a) 1.50 mm, (b) 2.50 mm and (c) 3.50 mm? Include a diagram of the situation including the Amperian loops used in the calculation.
