The coils of the magnetic circuit shown in figure are

The coils of the magnetic circuit shown in figure are connected in series so that the mmf’s of paths A and B both tend to set up flux in the center leg C in the same direction. The coils are wound with equal turns, N1 = N2 = 100. The dimensions are: Cross-section area of A and B legs = 7 cm2 Cross-section area of C legs = 14 cm2 Length of A path = 17 cm, Length of B path = 17 cm, Length of C path = 5.5 cm, Air gap = 0.4 cm. The material is M-5 grade, 0.012-in steel, with a stacking factor of 0.94. Neglect fringing and leakage.
a. How many amperes are required to produce a flux density of 1.2 T in the air gap?
b. Under the condition of part (a), how many joules of energy are stored in the magnetic field in the air gap?
c. Calculate theinductance.
