A thruster includes a mass source, an ejection outlet, and a channel forming an ejection path from the mass source to the ejection outlet. Multiple annular current paths form loops such that current flow along the loops is transverse to ion flow along the ejection path. The current paths are driven by current supply circuitry to create a selected current distribution proximate to the channel Un propulseur comprend une source de masse, une sortie d'éjection et un canal formant un trajet d'éjection de la source de masse à la sortie d'éjection. De multiples chemins de courant annulaires forment des boucles de sorte que le flux de courant dans la longueur des boucles est transversal au flux d'ions dans la longueur du chemin d'éjection. Les chemins de courant sont commandés par un ensemble de circuits d'alimentation en courant pour créer une distribution de courant sélectionnée à proximité du canal.
