Question

A coaxial cable has an inner solid conductor with a radius of a/10 and an outer conducting shell of radius of a. The cross section is as shown below. The inner conductor carries a current of magnitude I with uniform current density within it into the page, and the outer shell carries the same current out of the page. Using Ampere’s Law, find the magnetic field magnitude in each region as a function of radius (in the solid conductor, between the two conductors, and outside the outer conductor). Sketch a graph of the magnetic field magnitude as a function of radius for r = 0 to r = 1.5a roughly to scale and label the magnitude of the field at r = a/10, and a.
