    The torroidal transformer *is* axisymmetric, but when drawn
    that way the currents go around the small circle and the
    magnetic field is perpendicular to the page. I don't think
    femm solves this situation.

    Instead and approximation is to draw the cross sectional
    view in x-y form and set the total length to the median
    circumference.

    The "crunching" of the field at the inside curve won't show
    up, but it will get you started.
