Question: core 3 the symmetric ferromagnetic core as shown in area...

Question details

Core 3. The symmetric ferromagnetic core as shown in Area Fig. 2 has three windings. Windings A and B each have N turns and are wound on the two bottom legs of the core in the directions shown in the figure. Winding 1 has Ni turns and is wound on the center leg in the direction shown in the figure. The core dimensions are indicated in the figure. Assume a 5 percent increase in the effective area of the air gap due to fringing effects. a) Draw the equivalent magnetic circuit N, turns N turns N turns corresponding to Fig. 2. Find the flux that exists in each of the three legs of the core. Find the flux density in each of the legs? Find the self-inductances of each of the windings. Fig. 2 b) c) d)
