Simple nonlinear magnetic circuit with an air gap. Consider a magnetic circuit consisting of a thin toroidal ferromagnetic core with a coil and an air gap shown in Fig.5.3(a). The coil has N = 1000 turns of wire with the total resistance R = 50 Ω. The length of the ferromagnetic portion of the circuit is l = 1 m, the thickness (width) of the gap is l₀ = 4 mm, the cross-sectional area of the toroid is S = S₀ = 5 cm², and the emf of the generator in the coil circuit is = 200 V. The idealized initial magnetization curve of the material is given in Fig.5.3(b). With the use of MATLAB, find the magnetic field intensity (H) and flux density (B) in the core. In specific, write a MATLAB code that plots the magnetization curve of the core and

the load line of the circuit (in the same graph), and computes numerically and plots the operating point of the circuit. (ME5 12.m on IR) H
