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, = 1.16 A out of the page and the current in the outer conductor is I2 = 2.82 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 HT direction ---Select-- (b) Determine the magnitude and direction of the magnetic field at point b. magnitude HT direction ---Select- Need Help?

MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER The magnetic coils of a tokamak fusion reactor are in the shape of a toroid having an inner radius of 0.700 m and an outer radius of 1.30 m. The toroid has 820 turns of large-diameter wire, each of which carries a current of 16.0 kA. (a) Find the magnitude of the magnetic field inside the toroid along the inner radius. (b) Find the magnitude of the magnetic field inside the toroid along the outer radius. Need Help? Read It Watch It Submit Answer 11. [-/1 Points] DETAILS SERPSE10 29.3.P.021. MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER The magnetic field 41.0 cm away from a long, straight wire carrying current 6.00 A is 2930 nT. (a) At what distance is it 293 nT? cm (b) At one instant, the two conductors in a long household extension cord carry equal 6.00-A currents in opposite directions. The two wires are 3.00 mm apart. Find the magnetic field 41.0 cm away from the middle of the straight cord, in the plane of the two wires. nT (c) At what distance is it one-tenth as large? cm (d) The center wire in a coaxial cable carries current 6.00 A in one direction, and the sheath around it carries current 6.00 A in the opposite direction.
