Another simple nonlinear magnetic circuit. For the magnetic circuit in Fig.5.3(a), assume that l = 40 cm, S = S₀ = 2.25 cm², l₀ = 0.25 mm, N = 800, and I = 1 A. In addition, let the core be made from a nonlinear ferromagnetic material whose

initial magnetization curve can be linearized in parts as in Fig.5.2(b) with Hk = 1000 A/m and B_m = 1 T. Solve this circuit in MATLAB: plot, in the same graph, B-H relationships in both the core and the air gap, and plot (mark) in the graph the obtained numerical solutions for (H,B) in both regions, in addition to displaying the results in the Command Window.
