Can someone please help me analyze this magnetic circuit? I've got no idea...!
I want to calculate the flux in each leg.. so, let's take the first leg, flux 1
I know that flux = BA..
I calculate magnetizing force H = NI/l = 500/0.14 = 3571.42
but B = u0 * ur * H = 5000*(4*pi*10^-7)*3571.42 = 22.43
but flux = BA = 22.43 * 0.004 = 0.0089 Wb
Not even close to the answer! (4.887 mWb)
