1. A magnet structure (2) having three dimensions, one of which is height,
the magnet structure (2) having cutouts (4 to 7, 20, 21) extending along the height of the magnet structure (2) and forming groups of cutouts, the cutouts (4 to 7, 20, 21) of each group being interrupted, forming two parts each (4, 6, 5, 7, 20, 21) and leaving a material-filled gap between the two parts (4, 6, 5, 7, 20, 21) of a given cutout, the material-filled gaps of one group of cutouts (4 to 7, 20, 21) forming a portion of a one-piece heel (8a to 8d) common to all the groups of cutouts, the cutouts (4 to 7, 20, 21) delimiting between them individual magnets (3) held connected to one another by the heel (8a to 8d), characterized in that the material-filled gaps have a height between 2 and 20% of a total height of the cutouts 4 to 7, 20, 21, at least one material-filled gap between one cutout (4, 6) of one group being located at a height different from at least one material-filled gap between a cutout (5, 7) of another group, so that the heel portions (8a to 8d) of the different groups of cutouts extend at least partly over different height levels in the magnet structure (2).
