<p>An improved bar magnet (130) and method of construction, and an improved magnetic core (170) comprising an assembly of such magnets (130), for use in a processing station of an electrostatographic printing machine. The improved bar magnet (130) is formed of permanent magnet material having magnetic domains (D) therein that are magnetized along epicycloidal curve segments (E1, E2). The external magnetic flux density is improved over that of a conventionally-magnetized magnet. An injection mold (150) for inducing the particular epicycloidal alignement of magnetic domains (D) in the improved bar magnet (130) is provided.</p> |
