# Part AConsider a long coaxial cable made of two coaxial cylindrical conductors that carry equal currents I inopposite directions (see figure). The inner cylinder is a small solid conductor of radius a. The outer cylinderis a thin walled conductor of outer radius 6, electrically insulated from the inner conductor. Calculate the selfinductance per unit length of this coaxial cable.(L is the inductance of part of the cable and l isthe length of that part.) Due to what is known asthe "skin effect", the current I flows down the(outer) surface of the inner conducting cylinderand back along the outer surface of the outerconducting cylinder. However, you may ignore thethickness of the outer cylinder.IExpress your answer in terms of some or allthe variables I, a, b, and Ho, the permeabilityof free spaceto
