Consider a toroid with a rectangular cross section of 1 cm by 1 cm. The mean radius is 9 cm. Into this toroid, there is cut a 1.5 mm air gap. The toroid has 100 turns of wire. The permeability of the magnetic material is 3500 times the permeability of free space. Two windings are placed on the device such that positive current in one winding will ten1 to produce negative flux in the other winding. Suppose winding 1 has 30 turns; winding 2 has 15 turns. What is (a) the self-inductance of winding 1, (b) the self-inductance of winding 2, (c) the mutual inductance between the windings. Finally (d), if the current in the winding 1 is 6 A, and the current in winding 2 is -3 A, what is the flux linkage in winding 1? Ignore leakage inductance.
