A core with three legs is shown in Figure Pl-10. Its depth is 5 cm, and there are 400 turns on the center lcg. The remaining dimcnsions are shown in the figure. The core is composed of a stecl having the magnetization curve shown in Figure 1-10c. Answer the following questions about this core: (a) What current is required to produce a flux density of 0.5 T in the central leg of the core? (b) What current is required to produce a flux density of 1.0 T in the central leg of the core? Is it twice the current in part (a)? (c) What are the reluctances of the central and right legs of the core under the conditions in part (a)? (d) What are the reluctances of the central and right legs of the core under the conditions in part (b)? (e) What conclusion can you makc about reluctances in real magnctic corcs?
