ASK YOUR TEACHER PRACTICE ANOTHER The figure below is a cross-sectional view of a coaxial cable. The center conductor is surrounded by a nubber layer an outer conductor, and another rubber layer In a particular application, the current in the inner conductor is 1, 1-12 A out of the page and the current in the outer conductor is 1,286 A into the page. Assuming the distance d1.00 mm, answer the following 86 (a) Determine the magnitude and direction of the magnetic field at point a 112 If you construct an imaginary circe of radius of passing through point a, how much current passes through this circle u magnitude direction (b) Determine the magnitude and direction of the magnetic field at point b 112 magnitude You can approach this problem by finding the field produced by current 7, and the field produced by 1, and then adding them vectorially.
