An infinitely long, thin wire has a known current of 2i, which flows in the negative x-direction. It is surrounded by an infinitely long, hollow cylindrical wire so the wires have a common axis. The hollow wire has inner radius A and outer radius B. A known current i, which is uniformly spread over the hollow wire, flows in the positive x-direction in the hollow cylindrical wire.

Q.3 Consider an infinitely long coaxial structure shown in the figure below. Inner conductor has a radius a and outer conducting shell has a radius b. Thickness of the outer conductor is ignored as it is very small. Between two conductors, there is a magnetic material with permeability () = Mo a Assume that the current I is distributed uniformly over the cross-section of the inner conductor whereas it flows on the surface of the outer conductor. a) Find the...
