Question:

Question 7 A magnetic core is shown in Figure 1. Relative permeability of the core is 14 = 2000. Total number of winding turn
Question 7 A magnetic core is shown in Figure 1. Relative permeability of the core is 14 = 2000. Total number of winding turns in the left winding is NL = 100 and in the right winding is Nr = 10. Assume that the core cross section is uniform and the combined length of all air-gaps is much smaller than the dimensions of the core cross-section. Calculate the following: a) The magnetomotive force in the core if i = 2 A. b) The magnetic flux, Ø and magnetic flux density B in the Imm air gap if i= 2 A. c) Self inductance of the left coil from Figure 1. d) Mutual inductance between the left and the right coil from Figure 1. 35 cm 1 mm 35 cm T5cm 5 cm 2 mm 30 cm cm Figure 1: Magnetic core for Question 7
