摘要：

A simple technique is reported for comparing the magnetic shielding of YBa2Cu3O7-x superconductors in the form of ceramic discs and thin films with that of other materials. The experimental set-up uses a small transformer and lock-in amplifier and gives information about the magnetic shielding effect of superconducting and non-superconducting materials. The shielding factor was found to be strongly dependent on the thickness of the superconductor.
