Abstract

La présente invention concerne un aimant unitaire (1) de forme allongée, présentant un contour au moins partiellement ovoïde en comportant une première portion (1a) formant corps de l'aimant unitaire (1) présentant une plus grande section et s'étendant sur une plus grande longueur de l'aimant unitaire (1) qu'au moins une deuxième portion (1b) d'extrémité longitudinale pointant vers une extrémité longitudinale associée de l'aimant en diminuant de section en se rapprochant de l'extrémité longitudinale.
