Le NdFeB, Néodyme Fer Bore, représente le meilleur des matériaux magnétiques. La qualité exceptionnelle de ce matériau est affectée par l’action de la température de fonctionnement. Son utilisation n’est donc possible que dans des conditions définies. Il trouve des applications dans plusieurs secteurs et peut être utilisé dans des complexes magnétiques spécifiques afin d’obtenir des effets d’attraction remarquables avec un encombrement minimal.
