Chapter 1, Problem 1.13P
A core with three legs is shown in Figure P1-10. Its depth is 5 cm, and there are 400 turns on the center leg. The remaining dimensions are shown in the figure. The core is composed of a steel having the magnetization curve shown in Figure 1-10c. Answer the following questions about this core:
- What current is required to produce a flux density of 0.5 T in the central leg of the core?
- 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)?
- What are the reluctances of the central and right legs of the core under the conditions in part (a)?
- What are the reluctances of the central and right legs of the core under the conditions in part (b)?
- What conclusion can you make about reluctances in real magnetic cores?
