A transformer is constructed from a long wire carrying current I-ilocos() passes through a toroidal ferrite which has μ,-100, inner radius-a, outer radius-b, and depth (z dimension) - c. N turns of wire are wrapped tightly around the ferrite. The current creates a magnetic flux through the N-turn coil, which, in turn, induces a voltage, Vind, across the coil, as shown. a) Find an expression for the flux density, B, in the ferrite. b) Find an expression for the flux,...
