An image taken from the cross-sectional area of a coaxial cable consisting of a
solidinner conductor of Radius R, = 4 cm surrounded by a concentric cylindrical
tube of inner radius R, = 8 cm and outer radius R3 = 1m is given in the figure.
The inner conductor has the current density J = ar2 and the total current flows
in this cylinder is I, = 100A Here,a is a constant and r is the radial di stance
measured from the center. The outer cylindrical conductor carries a constant
current I, =100A distributed uniformly across its cross section. Total current Io
flows in opposite directions in both conductors. What is the magnitude of the
magneti c field B1 at a distance r = 2 cm and B2 at a distance r2 =9 cm ?
(H. = 4x10-7T.m/A, take the sign of the current coming out of the page as
positive).
