Consider a coaxial cable as shown in the figure. The cable consists of a solid inner conductor of radius n = 0.5 cm that is surrounded by a cylindrical tube of inner radius 12 = 0.8 cm and outer radius r3 = 1.9 cm. The conductors carry equal and opposite currents I = 4 A but the current density varies linearly with the distance from the center for the inner conductor (i = cr) while it is distributed uniformly for the outer conductor. Determine the magnetic field (in units of T (microtesla)) at a distance r = 1.2 cm from the axis. (Ho = 4* x 10-7N/A and * = 3.14) Answer:
