(a) State Ampere's Law.
(b) The figure shows a toroid with N total turns and a current I . Apply Ampere's Law to find the magnitude of the magnetic field inside the toroid and at a distance r from the axis of the toroid. [Make sure you draw a diagram to show the Amperian loop.]
(c) Apply Ampere's Law to find the magnetic field around an innitely long straight wire with current I.
