    This sort of testing isn't exactly my strong suit. However, there are
    ASTM standards that define accepted methods and equipment for doing
    these sorts of tests. These standards can be downloaded from the ASTM
    website for a nominal fee. There are a number of standards, and I
    don't know exactly which one would be most appropriate to what you are
    trying to do. A good place to start might be:

    A773/A773M-01 Standard Test Method for dc Magnetic Properties of
    Materials Using Ring and Permeameter Procedures with dc Electronic
    Hysteresigraphs
    http://www.astm.org/DATABASE.CART/PAGES/A773A773M.htm

    or perhaps at http://www.normas.com/ASTM/CONTENTS/Vol.03.04.html

    Several companies sell equipment for doing this sort of testing.
    I think Hirst Magnetics' "ARP03 Automatic Recording Permeameter" would
    be an example of such an instrument (is this right, Robin?), or maybe
    Walker Scientific:
    http://www.walkerscientific.com/Products/Product_Lines/Magnetic_Analysis/Hysteresisgraphs/hysteresisgraphs.html

    In any case, you should probably also talk to your material suppliers.
    These vendors have a financial interest in helping you to pick a
    material that will suit your needs.

    Dave.
