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 aparticular application, the current in the inner conductor is I₁ = 1.04 A out of the page and the current in the outer conductor is I2 = 2.90 A into the page. Assuming thedistance d = 1.00 mm, answer the following.412(a) Determine the magnitude and direction of the magnetic field at point a.magnitude 208direction upward(b) Determine the magnitude and direction of the magnetic field at point b.magnitudedirection238You can approach this problem by finding the field produced by current I₁ and the field produced by I2 and then adding them vectorially. μTdownward
