Two long straight cylindrical wires each of radius a are placed at a seperation d. Both the wires carry equal and opposite current of magnitude I. F ind the induced (L) per unit length of this arrangement. Neglect magnetic flux inside the wires.

and in receiving signals in television cable systems. Model a long coaxial cable as a thin Coaxial cables are often used to connect electrical devices cylinder of radius a as in figure. The conductors carry the same current I in opposite directions. calculate the inductance L of a length l of this cable. such as your video system
