[answerhappygod]

A coaxial cable is made up of a cylindrical conductor with
radius R1 and another conductor in the shape of a cylindrical
crown, coaxial with the first, and with radii R2 and R3. The
same intensity I circulates through both conductors, but in
opposite directions, outgoing in the cylinder (the intensities are
distributed homogeneously both in the cylinder and in the
crown).
