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.

An infinitely long, straight, cylindrical wire of radius R carries a uniform current density J. Using symmetry and Ampere's law, find the magnitude and direction of the magnetic field at a point inside the wire. For the purposes of this problem, use a cylindrical coordinate system with the current in the +z-direction, as shown coming out of the screen in the top illustration. The radial r-coordinate of each point is the distance to the central axis of the wire, and...
