Note how closely the B-H curve of cast steel in given figure(a) matches the curve for the voltage across a capacitor as it charges from zero volts to its final value.

a. Using the equation for the charging voltage as a guide, write an equation for B as a function of H = [B f(H)] for cast steel.

b. Test the resulting equation at H 900 At/m, 1800 At/m, and 2700 At/m.

c. Using the equation of part (a), derive an equation for H in terms of B [H = f(B)].

d. Test the resulting equation at B = 1 T and B = 1.4 T.

e. Using the result of part (c), perform the analysis of Example, and compare the results for the current I.
