Problem 4 The cross-section of an infinite co-axial cable is shown to the right. The inner conducting wire has radius a and carries a current 2/ INTO the page distributed evenly throughout the wire. The wire shell ? is surrounded by two thin conducting shells. Shell 1 carries a current / OUT OF THE page. Shell 2 carries a current of 3/ O shell ] o O OUT OF THE PAGE. O O (a) Draw the magnetic field in all regions: I, II, III, and IV (b) Show how the general form of Ampere's law is converted O O O to a form useful in cylindrical symmetry. (c) Compute the magnetic field in all regions, I, II, Ill, and II O O IV. Be sure to report the field as a vector and clearly O state what current is enclosed (encircled) in each region. III O IV
