Abstract
An arrangement is provided for compensation for detrimental magnetic influence between two or more rows of transverse electrolytic pots or cells for producing aluminum, by electrolytic reduction in a molten bath, in which most of the current conducted from the rear side of a pot in the pot row to the succeeding pot in the row, is carried by two or more conductors underneath the pot. Another and smaller proportion of the current conducted to the succeeding pot in the row is conducted in its entirety around that short side of the pot which faces the magnetically dominating adjacent pot row. Preferably, this smaller proportion of the current amounts to a maximum of twenty percent of the total electrolysis current.
