We have measured the effect of the mass and pole strength of a magnet on its equilibrium levitation height z over a superconducting disk of YBa/sub 2/Cu/sub 3/O/sub 7/. A simple image force model gives the observed dependence of z on the mass and pole strength, but not the observed proportionality factor.
