A simple torsion balance is described which is used to measure the levitation force on a magnet as a function of height above bulk samples of the new highTcsuperconductors. Results are presented for a the YBa2Cu3Ox(Tcsim;90 K) and the Tlhyphen;Bahyphen;Cahyphen;Cuhyphen;O (Tcsim;120 K) superconducting systems. Possible uses for the balance are discussed.
