The figure below shows the cross section of a long conducting coaxial cable with a = 2.00 cm, b = 1.80 cm, and c = 0.40 cm. The inner conductor carries a current of I = 120 A that is uniformly distributed throughout its cross section and is going out of the page; the outer conductor also has the same current (uniformly distributed) but going into the page. Find the magnitude and direction (CW or CCW) of the magnetic fields at the following radii. (a) r = 3.00cm (b) r = 1.00cm (c) r = 1.90cm
