ResumoA 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 high Tc superconductors. Results are presented for a the YBa2Cu3Ox (Tc∼90 K) and the Tl-Ba-Ca-Cu-O (Tc∼120 K) superconducting systems. Possible uses for the balance are discussed.
