Abstract
Amélioration du procédé selon la revendication 1 du brevet principal. On fait passer le conducteur 30 à travers un champ magnétique extérieur comprenant au moins deux zones 39 et 40 séparées dans l'espace qui sont disposées l'une après l'autre en direction longitudinale du conducteur et dont les champs 41, 42 sont tournés l'un par rapport à l'autre d'un angle prédéterminé en direction périphérique du conducteur. Application possible au contrôle de supraconducteurs de toutes sections dans des câbles, électro-aimants ou machines électriques.
