Hello Chris,
It is my guess by what you say it may be possible to create a spring with=
=20
just about any relationship like fitting the curve of force like any graph=
=20
of a conic section ?
.
i Geoff,
    Probably up to cubic over small ranges.
.
I understand magnetic attraction to be log base two ?
ouble the distance and divide the force by four ?
Same with electrostatic ??
    No, It's more complicated. You have two poles on every magnet. The=20
force between any two poles is inverse square law, but the force on a=20
magnet involves both poles. So there may be a rotational as well as a=20
linear forces.=20

    No, It's more complicated. You have two poles on every m=
