The coaxial cable shown in the figure(Figure 1) consists of a solid inner conductor of radius R1 surrounded by a hollow, very thin outer conductor of radius R2. The two carry equal currents I, but in opposite directions. The current density is uniformly distributed over each conductor. Find expressions for the magnetic field within the inner conductor? Find expressions for the magnetic field in the space between the conductors? Find expressions for the magnetic field outside the outer conductor? in terms of r R1 R2 and I
