Aluminium Smelter and Method to Compensate for a Magnetic Field Created by the Circulation of the Electrolysis Current of Said Aluminium Smelter

Aluminum smelter comprising at least one row of electrolytic cells arranged transversely in relation to length of said at least one row, a first electrolytic cell of the row of electrolytic cells comprising anode assemblies and rising and connecting electrical conductors to the anode assemblies, characterized in that the rising and connecting electrical conductors extend upwardly along two opposite upstream and downstream longitudinal edges of the first electrolytic cell for conducting electrolysis current to the anode assemblies, and in that the aluminum smelter includes:

• at least one first electrical compensation circuit extending beneath the electrolytic cells, said at least one first electrical compensation circuit being configured to be traversed by a first compensation current designed to flow under the electrolytic cells in an opposite direction to a global direction of flow of the electrolysis current,
• at least one second electric compensation circuit extending over at least one side of said at least one row of electrolytic cells, said at least one second electric compensation circuit being configured to be traversed by a second compensation current designed to flow in a same direction as the global direction of flow of the electrolysis current.
