The right side of the magnetic circuit shown is made of cast iron while the other three sides are made of soft cast steel. (a) Calculate the mmf needed to produce a flux of 25X10 Wb in the core, (b) Find the value of the self inductance, L, for those operating conditions 15 cm- 30 cm 1. 600 turns 350 turns 1.5 +x=² +-10cm depth = 0.025 m cure Dimensions in cm. 15 cm 15 cm I 1 10 200 0.5 04 0.2 Nickel Q7(12 p.) The magnetic circuit shown is comprised of a laminated core of steel with an air gap g = 0.25 cm and has an exciting winding of 350 turns. The magnetization curve for the iron is shown. The stacking factor is 0.95. Neglect leakage and fringing.
