(b) Figure Q3(b) shows a magnetic circuit with two different material, with a mean cross- sectional area of 25 cm?. The mean core length of steel, Lsı and Ls2 is 20 cm and 15 cm, respectively. The mean core length of iron, Ln and Ln is 20 cm and 14 cm, respectively. The air gap length, Lag is 1 cm. Relative permeability of steel and iron is 7000 and 4000 respectively. Fringing effect is excluded. Calculate: Steel Iron Ls1. L12 N2 Lag Steel N1 Iron LI1 Ls2 Figure Q3(b) (i) Total reluctances of this magnetic circuit. (ii) Total magnetomotive force required to produced 60 µWb of flux across the air- gap. (iii) Number of turns in coil 1, N1 if both electrical source supply the same amount of current, 5A, assume N1 = N2. 2)
