The figure below is a cross-sectional view of a coaxial cable. The center conductor is surrounded by a rubber layer, an outer conductor, and another rubber layer, In a particular application, the current in the Inner conductor is I, = 1.10 A out of the page and the current in the outer conductor is I, = 2.98 A Into the page. Assuming the distance d = 1.00 mm, answer the following. (a) Determine the magnitude and direction of the magnetic field at point a. 37.6 magnitude if you construct an imaginary circle of radius of passing through point a, how much current passes through this circle? UT direction upward (b) Determine the magnitude and direction of the magnetic field at point b. 1.099 X magnitude You can approach this problem by finding the field produced by current I, and the field produced by J, and then adding them vectorially, IT direction downward
