Using the magnet thickness and airgap thickness to construct a load line (Bd/Hd) to determine the operating point on the normal curve, and then adding 1 (Bd/Hd +1) I should be able to have a line parallel to this to intersect where the intrinsic curve drops 10% and read the reverse field required to demagnetize to this point.
What I don’t understand is that if I increase the airgap and go through the same procedure it appears that it would take less reverse field to demagnetize the magnet. What is wrong with my thought process?
