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.

โฆ Synopsis
The magnetization of a V3Ga superconducting tape between two successive flux jumps has been experimentally determined by means of search coil measurement in an increasing field perpendicular to the surface. On the basis of these experimental results, an attempt is made to determine theoretically the current induced region as a function of only one parameter across the width, in order to calculate approximately the magnetization.
The influence of the superconductor temperature rise on ffTe magnetization is also calculated. The comparison between measured and calculated magnetization shows good agreement except when the current induction front is very close to the tape edge at the beginning of the application of the field.
