The magnetic circuit shown in Figure 2 is made of silicon steel, for which the B-H curve is provided in Figure 3. Each coil has 500 turns. It is required to establish a flux of 3.6 mWb in the air gap, by applying the same current to each coil, i.e., |I 1|=|I 2| (and note their orientation).

What is the required current? The dimensions of the magnetic circuit are as follows:

Cross-sectional area of all legs: 30 cm2

Length of path A: 90 cm

Length of path B: 90 cm

Length of path C: 45 cm

Air gap length: 0.4 mm
