Abstract

L'invention concerne un ensemble de préhension-maintien magnétique servant à manipuler des objets magnétiques agencés sous forme de matrice, notamment des particules portant des échantillons chimiques. Au moins une partie des objets magnétiques peuvent être déplacés simultanément dans une nouvelle position, sans modification de leur affectation conditionnée par la matrice, au moyen d'une force magnétique qui agit partiellement sur la matrice. L'objectif de l'invention est d'éviter des superpositions de champs magnétiques locales globales ainsi qu'une réduction de la force magnétique exploitable, et de permettre à cet ensemble de fonctionner de manière économique. A cet effet, à chaque objet magnétique est associé un champ magnétique de maintien auquel est superposé un champ magnétique de préhension, mobile, agissant partiellement sur la matrice.
