1 Consider a coaxial cable which consists of an inner wire of radius a surrounded by an outer shell of inner and outer radii b and c respectively The inner wire carries an electric current i and the outer shell carries an equal current in opposite direction Find the magnetic field at a distance x from the axis where a x a b a x b c b x c and d x c Assume that the current density is uniform in the inner wire and also uniform in the outer shell DO O a b c Figung 25 WO d
