WebNov 26, 2024 · The B-H curve is usually used to describe the magnetization properties of such materials by characterizing the permeability , which is defined as: where and represent the magnetic flux density in tesla (T) … Web“Weird” B-H curves can result if you have entered too few points around relatively sudden changes in the B-H curve. Femm “takes care of” bad B-H data (i.e. B-H data that would result in a cubic spline fit that is not single-valued) by repeatedly smoothing the B-H data …
Re: [FEMM] BH curves, intrinsic?

WebMar 17, 2004 · I have the intrinsic BH curve of the metal. After editing all the BH curves for ferromagnetic metals in the actual FEMM library, I can see that the BH curves are not the "intrinsic curves" but that a term in ( 10^6 . H ) is added (probably to enter the "total" B at a given H). The curve that you should enter into femm is the "total" b that ... WebJan 7, 2016 · The Effective Nonlinear Magnetic Curves Calculator app can be used to generate the effective B-H/H-B curves for frequency-domain (time-harmonic) … WebWe see that the computed B-H curves overshoot in the unsaturated region.
