Question

 A ferromagnetic core is shown in Figure 1. The relative permeability of the core is
assumed to be 2500 and constant. There is a 5% increase in the effective area of
the air gap due to fringing effects. The depth of the core is given as 5 cm. 

The Rtotal is found to be 226.192k At/Wb

b) Calculate the magnetic intensity, H, in the left leg, bottom leg and the air gap. | 5 cm + + 5 cm 4 35 cm 15 cm ЗА 4 A 30 cm 500 turns 300 turns 0.1 cm 15 cm Figure 1
