Abstract
Novel methods of electronically modulating magnetic fields are described. The basic principle of the instant invention is based on the well known Meissner Effect. A superconducting element is placed within a magnetic field whose strength is much less than the critical field of the superconductor. The field flux is excluded out of the superconducting medium. When the superconductor is now forced into its mixed or normal phase by external means, the magnetic field around it is modified and thus modulation of that field near the superconductor surface is possible. Three distinct methods of modulating magnetic fields on the surfaces of superconductors are detailed and some applications disclosed.
