The cross-section of the three-winding magnetic system shown in the figure is uniformly 25 cm^2 everywhere. The numbers of turns are N1 = 3500, N2 = 2500, N 3 = 1500, and the lengths of the air gaps are lh1 = 2 mm, 1h2 = 1 mm, 1h3 = 3 mm. The relative permeability of the material is infinitely large, and leakage fluxes and flux deviations in the air gap are assumed to be negligible.
