Question

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 I1 = 1.14 A out of the page and the current in the outer conductor is I2 = 3.20 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.

magnitude	µT
direction	---Select--- to the left to the right upward downward into the page out of the page

(b) Determine the magnitude and direction of the magnetic field at point b.

magnitude	µT
direction	---Select--- to the left to the right upward downward into the page out of the page
