A magnetic circuit in the following figure is made of silicon steel, for which the B-H relationship is given as B = 2(1 – e¯s00) (T ), where B and H represent the magnitudes of magnetic flux density and magnetic field, respectively. Magnetic flux density is measured in Teslas. The outer legs have 500 turns each. It is required to establish a flux of 3.6 mWb in the air-gap by applying equal currents to both windings. What is the current in each winding? (Hint: Be careful, the B-H relation is not linear.) 50 (All dimensions in centimeters)
