Abstract: An elongated, magnetic flux impeding means is provided in the magnetically conductive shell of an electrolysis cell, and extends in a direction substantially perpendicular to the direction of a magnetic field component intermittent flow of current, in which a saturated mono-or polyvalent ether or a lower alkanoic acid is added to the reaction mixture.

Abstract: A plurality of elongated, magnetic flux conducting structures magnetically spaced adjacent the sides of a cell for producing molten aluminum by electrolysis. The magnetically spaced, flux conducting structures are effective to shield the cell from and to substantially reduce the strength of a magnetic field component extending within the cell in a direction substantially parallel to the length dimension of the elongated structures without substantially affecting magnetic field components extending in directions other than the magnetic field component extending parallel to the elongated structures.
