In figure, a magnetic flux of Fis generated with a constant current of i. The core material used has a relative permeability of 4000. Assuming that the mean cross sectional area that the magnetic flux passing through in core is A=4 [cm?] and there is no fringing in air gap, N= 1000 turns and i=10 [A], lai=2 [mm]. • what is the reluctance in air gap? • what is the total reluctance? • what are the flux and flux density in air gap? Remember: po= 4nx107 Answers: Rair= [At/Wb) Rtotal = AL/Wb] (Wb] B = 200 (mm] 2 (mm] 1000 turns 100 [mm) 10 (A] 180 (mm] In figure, a magnetic flux of Fis generated with a constant current of i.
