For values of B below the knee on the magnetization curve for silicon steel, approximate the curve

Question:

For values of B below the knee on the magnetization curve for silicon steel, approximate the curve by a straight line with μ = 5 mH/m. The core shown in Figure 8.16 has areas of 1.6 cm2and lengths of 10 cm in each outer leg, and an area of 2.5 cm2and a length of 3 cm in the central leg. A coil of 1200 turns carrying 12 mA is placed around the central leg. Find B in the
