An image taken from the cross-sectional area of a coaxial cable consisting of a
solid inner conductor of Radius R, 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 = Cr and j, = C,r
, respectively, for which r is the radial distance from the center. Each conductor
carries the same total 1, in opposite directions. What is the magnitude of the
magnetic field B at a distance r = 1 cm and B2 at a distance r2 = 8 cm ?
(R, = 4 cm ; R, =7 cm ; R, = 9 cm ;I, = 2 A; Ho = 4nx10-7 T.m/A. Take
