Consider a cylindrical cable designed to carry current to and from a power supply. The current flows along the length of the cylinder. Choose the z axis to be along the centre of the cylinder, and let s , o be the other two standard cylindrical coordinates. A current +I flows between 0 < s < 81 in the +î direction, and a current - I flows between S2 2782 O B = us ??? 2x
