For the transformer shown in Figure P13.18, N = 1,000 turns, l1 = 16 cm, A1 = 4 cm2, l2 = 22 cm, A2 = 4 cm2, l3 = 5 cm, and A3 = 2 cm2. The relative permeability of the material is μr = 1,500.

a. Construct the equivalent magnetic circuit, and find the reluctance associated with each part of the circuit.

b. Determine the self-inductance and mutual inductance for the pair of coils (that is, L11, L22, and M = L12 = L21).
