A. Find the current, I, required to establish a flux 0= 2.4x10-4 Wb in the
magnetic circuit of Figure. Here, Area(throughout) = 2x10-4 m², lab = Lef= 0.05 m
laf = lbe = 0.02m, lbc = ldc, and the material is sheet steel.
b. Compare the mmf drop across the air gap to that across the rest of the magnetic
magnetic
circuit. Discuss your results using the value of u for each material.
(NOTICE: find the magnetization curve in page 29 Figure 1.32 in Reference 00
Motor and controlling. The reluctance of sheet steel should be taken into
calculation)
