Abstract
Arrangement is disclosed for compensating detrimental magnetic influence on longitudinally oriented pots (U.sub.3) in a pot row, from the current in one or more adjacent pot rows, in plants for producing metal, for example aluminum, by electrolytic reduction of a molten bath. Two substantially symmetrical groups (k.sub.31, k.sub.32) of cathode taps located at opposite sides of the positive end of the pot, are each connected to a separate compensation bus bar (X, Y) so located in relation to the pot (U.sub.3) that they form a current loop around the cathode in a clockwise or in a counter-clockwise direction, depending upon whether a positive or a negative vertical magnetic field is to be compensated for.
