In figure, a magnetic flux of F is 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 [cm2] and there is no fringing in air gap, N= 1000 turns and i=10 [A], lair=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: µ0 = 4πx10-7
