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 930 turns of large-diameter wire, each of which carries a current of 10.0 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.
