A ferromagnetic core is shown in Figure 1. There is a small gap of0.07 cm in the structure of the core and the other dimensions' values of the core are shown in the Figure 1. The depth of the core is 5 cm. The rdative permeability of the core is 850 and has 300 turns of coil wire. Assumethat fringing in the airgap has increased the effective cross-sectional area by 5 percent. a) Draw the magnetic equivalent cireuit. Define all the label in your sketch correctly. b) Calculate the total reluctance, Rrotal of the ferromagnetic core including the air gap. c) If3 A input current is injected to the coil, determine the total flux, Orotal that will be produced. d) Determine the magnetic flux density, B in the air-gap and in the bottom core of the magnetic system. 15 cm 5 cm 10 ст 0.07 cm 5 cm 20 cm 300 tums 10 cm Figure 1: Ferromagnetic Core

Voltage sags due to short circuit and earth faults are the cause for the vast majority of equipment problems. Electronics equipment become more susceptible to voltage sag, hence the companies experience production stoppages. Voltage sag analysis is very complex issue. Based on voltage sag randon factors describe on it.
