In the magnetic circuit shown in Figure (a) the coil of 500 turns carries a current of 4 A. The air-gap lengths are g1 = g2 = 0.25 cm and g3 = 0.4 cm. The cross-sectional areas are related such that A1 = A2 = 0.5A3. The permeability of iron may be assumed to be infinite. Determine the flux densities B1, B2, and B3 in the gaps g1, g2, and g3, respectively. Neglect leakage and fringing.
Determine flux in the central limb: For the magnetic circuit shown in Figure the value of flux in the right limb is 0.48 m Wb and the number of turns wound on the central limb
