Question 1 (50%) A ferromagnetic core with an air gap is shown in Figure 1. The relative permeability of the core is 6000, and the number of turns on the coil is 1000. Due to the fringing effect, the effective area of the air gap is 5% larger than its physical size. Assume that the input current is 1 A. Calculate: a) The total flux in the core b) The flux densities of the four sides of the core c) The flux density at the air gap www.p CH C C ---- C 11 N 1,000 turns 10 cm- 4 Figure 1- A F 30 cm- 0.05 cm 153 cm Depth = 5 cm 10 cm 30 cm 10 cm Question 1 (50%) A ferromagnetic core with an air gap is shown in Figure 1.
