摘要：In an aluminum electrolytic cell in which alumina is electrolyzed by electriccurrent flowing between an anode electrode and a cathode electrode, ferromagneticrods 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 fieldcreated in the cell by the current to produce a magnetic field containing a verticalcomponent that decreases a gradient of a vertical component of the magnetic fieldcreated by the current. The magnetic member may be disposed above or below analuminum metal layer or above the anode electrode. In the last mentioned case, aferromagnetic bar may be wound about an anode supporting rod to form a coil havingopposite terminals extending in the horizontal direction.
