Given a magnetic circuit as shown in Figure Q3(a)(i) where the core is a cast steel. B- H curve for the cast steel is shown in Figure Q3(c)(ii). The center limb has a cross- sectional area of 600 mm² and each of the side limbs has a cross sectional area of 450 mm². A coil of 200 turns is wound on the central limb. Neglect any magnetic leakage and fringing effect. You are required to provide the equivalent Ampere's Circuital Law model with the detail of the labelling and also investigate the m.m.f. and current values that are required to establish a flux of 8.4 x 10“ Wb in the centre limb.
