Longitudinally arranged electrolytic cells for the production of aluminum in particular, incur high investment and operating costs due to the arrangement of the busbars outside the cells. These busbars induce magnetic fields which in turn cause stirring effects in the metal in the cell. If at least the last cathode bar ends (in terms of the direction of flow I of current) on both sides of the cell are connected via busbars to the end of the anode beam at the current ingoing end of the next cell or the other end of the anode beam, this gives rise to an asymmetry which eliminates the harmful effects of the magnetic fields and helps to lower the investment and operational costs.
