Abstract
A magnetizing apparatus is for magnetizing a magnetizable object. The magnetizing apparatus comprises a programming unit being shaped in such a manner that, when the programming unit is positioned adjacent to the magnetizable object and an electrical programming signal is applied to the programming unit, the magnetizable object is magnetized so as to form at least two magnetically encoded regions with different magnetic polarity along an extension of the magnetizable object.
