6. A portion of a long, cylindrical coaxial cable is shown in the figure. The innerconductor and the outer conductor are separated by an insulating medium. A current /flow down the inner conductor or radius r₁, and this current is returned in the outerconductor that is extending from radius 12 to 13. The current is uniformly distributedacross the cross section of each conductor.13a) Applying a relevant criterion (specify), derive expressions for the magnitude of themagnetic flied in each region: B₁ for r r3 where r is the radial distance from the axis of the coaxial cable.b) Produce a graph showing the magnetic field (y-axis) as a function of the radialdistance r (x-axis). Mark B₁, B2, B3 and B4 appropriately on the graph.
