Abstract
In an aluminum electrolytic cell in which alumina is electrolyzed by electric current flowing between an anode electrode and a cathode electrode, ferromagnetic rods are disposed on the anode electrode in parallel with a shorter end wall of the cell. The ferromagnetic rod is magnetized by a horizontal component of a magnetic field created in the cell by the current to produce a magnetic field containing a vertical component that decreases a gradient of a vertical component of the magnetic field created by the current. The magnetic member may be disposed above or below an aluminum metal layer or above the anode electrode. In the last mentioned case, a ferromagnetic bar may be wound about an anode supporting rod to form a coil having opposite terminals extending in the horizontal direction.
