The magnetic circuit of Problem 1.1 has a nonlinear core material whose permeability as a function of Bm is given by where Bm is the material flux density.
a. Using MATLAB, plot a dc magnetization curve for this material (Bm vs. Hm) over the range 0 < bm="">< 2.2="">
b. Find the current required to achieve a flux density of 2.2 T in the core.
c. Again, using MATLAB, plot the coil flux linkages as a function of coil current as the current is varied from 0 to the value found in part(b).
