3. A series magnetic circuit has an iron path of length 50 cm and an air-gap of length 1 mm. The cross-sectional area of the iron is 6 cm2 and the exciting coil has 400 turns. Determine the current required to produce a flux of 0.9 mWb in the circuit. The following points are taken from the magnetization characteristic : Flux Density (Wb/m²) Magnetizing Force (At/m) 1.2 500 1.35 1.45 1.55 1000 2000 4500
