    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.
