Abstract
A fixture for multi-pole magnetization of a magnetizable part has two carrier plates, each having a serpentine channel therein, with an electrical conductor contained in each channel. The electrical conductors each have a thin portion having a cross section which is less than the cross section of the remainder of the conductor. The thin portions of the conductors are mounted so as to be movable in the channels. A part to be magnetized is arranged between the thin portions of the conductors, and the conductors are supplied with a current surge. As a result of the flexibility, and the movable mounting, of the conductor portions, they are caused by the power surge to move against the magnetizable part, thereby creating differently magnetized, adjacent regions in the part, having a boundary therebetween coinciding with the location of the thin portions. A magnet is thereby achieved which is substantially the same as joined individual magnets of opposite polarity.
