Re: [FEMM] Need help in analytical fitting of steel B-H curve

["Chris Holt" <chris.c.holt@xxxxxxxxxx>]

One approach is an exponential function like that
described in Paul Victor Birke's 1998 post to
sci.physics.electromag, which can be seen at
http://groups.google.com/groups?selm=364EE79A.F279CFE%40home.com&oe=UTF-8&output=gplain

I've also tried this approach with a further factor on the
exponential term and have obtained some reasonable-
looking B-H curves.
