Q: Find the current I_N, required to establish a flux of 2 mWb in the air gap of the magnetic structure shown in the figureThe structure is made of silicon sheet steel, and its magnetization curve is also shown. Assume that the coil has 500 turns, and the structure has the dimensions given
l1=40cm A1=40 cm2 l3=l4=26 cm A3=A4=25 cm2
l2=24cm A2=12 cm lg=25*10-3 Ag=26 cm2
