A coaxial cable consists of a solid center conducting wire and an outer coaxial cylindrical conductor. The space between the conductors and the outer insulation are made of a good insulating material e.g. neoprene. The figure below shows a cross section of such a cable. The current in the center wire is 2.44 A out of the page and the current in the outer conductor is 4.21 A into the page. If the distance a is 2.00 mm, determine the following. ® 1₂ P₂ @ ol, ® -2a- -3a- (a) the magnitude and direction of the magnetic field at the point P₁ magnitude T direction vertically upward toward the top of the page (b) the magnitude and direction of the magnetic field at the point P₂ magnitude direction vertically downward toward the bottom of the page
