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.

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.
