R2 lo R3 Ri An image taken from the cross-sectional area of a coaxial cable consisting of a solid inner conductor of Radius R1 surrounded by a concentric cylindrical tube of inner radius R2 and outer radius R3 is given in the figure. The inner conductor and outer conductor (cylindrical tube) have the current density ji = C,r and j, = C2r , respectively, for which r is the radial distance from the center. Each conductor carries the same total I, in opposite directions. What is the magnitude of the magnetic field B, at a distance r, = 2 cm and B, at a distance r, = 7 cm ?
