A long coaxial cable (Fig.) consists of two concentric cylindrical conductors with radii a and b, where b>> a. Its central conductor carries a steady current i, and the outer conductor provides the return path, (a) Calculate the energy stored in the magnetic field for a length l of such a cable. (b) What is the inductance of a length l of the cable? You want to wind a coil so that it has resistance but essentially no inductance. How would you do it?
