Abstract

Système de génération de champ magnétique La présente description concerne un système (200) de génération de champ magnétique comprenant un circuit magnétique comportant : - un pôle central (220) disposé au-dessus d'un plan (XY), l’axe dudit pôle central s’étendant selon une direction orthogonale au plan ; - au moins deux pôles planaires (216A, 216B, 216C, 216D) disposés symétriquement sur le plan par rapport à l’axe du pôle central, chaque pôle planaire étant porté par une portion du circuit magnétique ; et - au moins deux bobines (230A, 230B, 230C, 230D), dont au moins une bobine associée à chaque pôle planaire, chaque bobine associée à un pôle planaire entourant la portion de circuit magnétique portant ledit pôle planaire ; deux bobines associées à deux pôles planaires différents étant adaptées à être connectées à deux circuits d’alimentation distincts ; chaque circuit d’alimentation étant adapté à faire circuler dans au moins une bobine à laquelle elle est connectée un courant d'intensité et de sens déterminés en fonction d’un champ magnétique souhaité et de l’orientation dans le plan du pôle planaire associé à ladite bobine.
