A toroid having a square cross section, 3.00 cm on a side, and an inner radius of11.0 cm has 500 turns and carries a current of 0.800 A. (It is made up of a square solenoid bentinto a doughnut shape.)
(a) What is the magnitude of the magnetic field insidethe toroid at the inner radius?
T
(b) What is the magnitude of the magnetic field inside the toroidat the outer radius?
T
