4) The figure shows a cross section of a long conducting coaxial cable and gives its radii (a, b, c). Equal currents I that are going in the same direction are uniformly distributed in the two conductors. Assume a = 2.00 cm, b = 1.5 cm, c = 0.50 cm, and I = 5 A. Determine the magnitude of the magnetic field at r = 1.60 cm. You must show the entire Ampere's Law derivation to receive credit. Answer: B = 7.36 x 10-5 T -----
