Abstract
A superconducting magnet for a MAGLEV vehicle has flux perturbation shielding rings mounted to the core common with superconducting magnetic coils. These rings resist rapid flux perturbations occurring in the superconducting magnet as a result of normal operational transients. The rings are, in effect, short-circuited coils fabricated from metal. One or more sets of these shielding rings may be employed along the length of the core for achieving flux regulation.
