    Hi All & David,

    I have attached a rather simple set-up of a magnet positioned mid way vertically
    between two parallel ferromagnetic bars and at the left end.

    A analysis of the forces acting on the magnet (via a clockwise contour around
    the 4 points near the magnet's corners) shows a net generation of a negative (to
    the left) x axis force where there should be a positive (to the right) x axis
    force as the magnet attempts to self centre in the middle of the two parallel
    bars.

    Comments please.

    Greg Watson
