Abstract

The magnet (1) has, on its lateral faces (1b), at least two grooves (2) (or groups of grooves) which are inclined with respect to the base and located on two opposite zones of the magnet; the latter is then embedded in an injected plastic. These magnets find applications in multiple transducers such as the drives for loom or printer needles. <IMAGE>
