ABSTRACT:
An arrangement is provided for compensating for detrimental magnetic horizontal fields at the plus or upstream end of longitudinally oriented pots in plants for melt-electrolytic production of aluminium, in particular where compensation for vertical magnetic influence from one pot row to another is provided for by utilizing an anode current supply to the minus or downstream end of each pot. A smaller proportion of the current supply to the minus end of the pot takes place through one or more conductors being located underneath the pot in the longitudinal direction thereof, said smaller proportion of the current supply being preferably no more than 20% of the total anode current supply.
