#41 Figure 4 Shows a magnetic circuit with airpaps P1=P2=f3=1mm and Coils 1 = laaturns and M2= Zaa turns. The cross Sectional area A of the circuit is 20amm. Assume the permeability of the care material approaches infinity and the fringing effect is negligible. Calculate. at the self and mutual inductances b). the total magnetic energy stored in the System if the currents in the coils are {1= 12= 1A; A 9 7178 W 92 Figure 4 A N2
