Consider a cylinder coaxial cable. The center conductor is solid with a radius of R, while the outer conductor is hollow inner radius a and outer radius b. Both conductors have the same total current l (of uniform current density), moving in the opposite direction of each other. Find the magnitude of the magnitude field as a function of r (where r = 0 at the central axis) in the interval a is less than or equal to r which is less than b.
I am unsure of how to start this problem and set up the correct equation.
