Abstract (en)

[origin: US4379276A] A process and apparatus for permitting the magnetization of materials in the form of sheets or strips, such as magnetic rubber, wherein one or two stacks formed by flat main magnets 1 adjacent to ferromagnetic pole pieces 2 in the vicinity of which (or between which) travels the strip to be magnetized. The main magnets adjacent to the same pole piece having opposing magnetizations as well as the magnets located face to face in each of the stacks. The device can be completed by field magnets delta and intermediate magnets 9.
