Example 1-1. A ferromagnetic core is shown in Figure 1-7a. Three sides of this core are of unifonn width. while the fourth side is somewhat thinner. The depth of the core (into the page) is 10 cm. and the other dimensions are shown in the figure. There is a 2()()'" turn coil wrapped around the left side of the core. Assruning relative penneability I-Lr of 2500. how much flux will be produced by a I-A input current?
