Youngdahl, C A

A method for dissipating a remanent field, created when a magnetic field is brought into contact with a superconductor, comprising the steps of (1) providing a ceramic superconductor; (2) continuously or intermittently applying an AC current to the ceramic superconductor; (3) gradually removing the AC current until the undesired remanent field is dissipated.
