    Hello Everyone

    First post so a big thankyou to David Meeker for his creation :-)
    (Sorry for using a smilie)

    Has anyone experience they could share in running the following type
    of analysis. I have searched the archive but to no avail.

    I am trying to model the process of magnetizing a ferrite magnet. Say
    by running current carrying wires immediately next to its surface.
    This is a simplification but will suffice.

    The magnetized ferrite block is then removed from the wires and its
    effect (Force and Torque) on a second magnet is observed.

    I cannot see a way to ascribe the resulting field pattern to the now
    magnetized ferrite block. Does anyone know how to set the magnitude
    of the magnetization as a function of position across the block.
    eg less further away from where the wires were. Setting the
    magnetization angle is fairly straight forward and I can calculate
    torques using coenergy methods but cannot see how to set the above or
    a radial field distribution.

    Maybe this is a problem for the hidden powers of LUA.
    Any advice would much appreciated
