hello everybody!
I have a problem with ampere's low.assume that we have an iron core with a winding in on side of it as sketched in the below image.we want to find H(magnetic field strength) and B(magnetic flux density) in the core in different condition shown in the right of image .the cross-section area of the core is constant in every points and we don't want to ignore core reluctance.in all of the conditions,the ampere loop, winding turns and the current pass through the conductor is constant. according to ampere's low, H must be equal in all of these conditions.but,simulations have different result and H change in each of the conditions.intuitively,the H should be different because of changing in the distance of winding from core.so,why ampere's low can't show the difference in H?
