Abstract
Résumé

This article outlines the experimental realization of the Roberts–Busse kinematic dynamo model at the Forschungszentrum Karlsruhe. Essential observations of the spatial and temporal structures of the self-induced magnetic field and features of its saturation mechanism are presented and the experimental findings are compared with predictions from model calculations.

L'article ci-dessous souligne les traits essentiels de la réalisation expérimentale du modèle de dynamo cinématique de Roberts et Busse, au Forschungszentrum Karlsruhe. Nous y présentons les caractéristiques essentielles concernant les structures spatiales et temporelles du champ auto-entretenu. Nous comparons les observations expérimentales avec les prédictions de modèles et de simulations numérique.
