Zusammenfassung:A process and apparatus for permitting the magnetization of flexible hard magnetic materials in the form of sheets or strips, such as magnetic rubber, wherein opposing arrays (10) formed from alternating magnetic disks and flux conducting elements are used in sets of two with opposing polar moments such as to induce a magnetic flux in the gap between the disks. A material to be magnetized is passed between the array sets (35) and consequently imprinted with magnetic poles. The magnetized properties of the material is enhanced by passing the material through a second set (38) of arrays which are axially offset with respect to the first set of arrays. This enhances the residual induction of the sample and significantly improves the pull strength of the material.
