From the dc magnetization curve of figure it is possible to calculate the relative permeability Âľr = Bc/(Âľ0Hc) for M-5 electrical steel as a function of the flux level Bc. Assuming the core of figure to be made of M-5 electrical steel with the dimensions given in Example 1.1, calculate the maximum flux density such that the reluctance of the core never exceeds 5 percent of the reluctance of the total magnetic circuit.
