A wire carries a current in some direction, this current is uniformly distributed along the transversal section (it's circular) of the wire (inside all of the wire except the surface). The same current goes back along the surface (this is due a very thin insulating material between the surface an the inside of the wire, wich separates the currents). Find the self-inductance along the wire per unit of length

Calculate the self-inductance per unit length for a coaxial cable. As a model for the cable, assume that current flows uniformly through a circular cross-section off radius R, and then returns along the surface of the cable (so that there is no magnetic field outside the cable). You can neglect the thin insulator that separates the current from the return current in your calculations.
