The properties of high T c superconducting bearings, consisting of a set of alternatingpolarity magnets and a superconductor, are studied in this paper. The superconducting bearing has a large surface area, contributing to levitation forces, and is zero-field cooled in liquid nitrogen. To investigat

โฆ Synopsis
When considering superconducting magnets with high stability requirements for the central induction flux, redistribution processes within the winding become important even when conductors with fine filaments are used. A model is introduced to calculate the changes of the central induction from magnet and conductor-dependent parameters. The results show good agreement, when compared with measurements.

A simple qualitative model is proposed to explain the fast initial change of the magnetic field of superconducting magnets which operate in the persistent mode. Using this model the additional component of the transport current which is induced by the decaying screening currents can be represented.
