Prob.l. A rectangular magnetic core shown in the below Fig, has square cross-section of area 16 cm". An air-gap of 2 mm is cut across one of its limbs. Find the exciting current needed in the coil having 1000 turns wound on the core to create an airgap mu of 4 m Wb. The relative permeability of the core is 2000. N=1000 2 mm 25 cm - - 20 cm
15 marks] B. A toroidal core with a mean diameter of 200 mm and a cross-sectional area of 800 mm has an air gap of length 1.1 mm cut in it Fringing and leakage of flux around the air gap may be neglected (i) Determine the current required in a coil of 1100 turns to produce a flux density of 1 T The relative permeability , of the core material (iron) may be assumed to be 3000 for this level...
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...
