Résumé
Nous avons étudié les variations de la distribution du courant dans les supraconducteurs à filaments multiples, dues à l'action de champs magnétiques extérieurs variables. Le changement d'une distribution non=uniforme à une distribution uniforme s'accompagne de pertes qui deviennent notables lorsque le courant de transport est proche du courant critique.
Abstract
We studied the change of current distributions in multifilamentary superconducting wires induced by the changing external magnetic field. The change of distribution from non-uniform into uniform one is accompanied by losses which become remarkable for the transport current near the critical current.
