    • A method for orienting a timepiece component including ferromagnetic material, where, on both ends of this component, two magnetic fields each attract it onto a pole piece, with an unbalance in the intensity of these fields around this component, in order to create a differential in the forces thereon and to press one of these ends onto a contact surface of one of the pole pieces, and to hold the other end at a distance from the other pole piece. A magnetic pivot includes such a component with two ends. It includes a guide device with surfaces of two pole pieces each generating a magnetic field attracting one of these ends, the magnetic forces exerted on the two ends being of different intensity, in order to attract only one end into contact with only one of these pole piece surfaces.
    • 一种用于定向包括铁磁材料的钟表部件的方法,其中,在该部件的两端上,两个磁场各自将其吸引到极片上,在该部件周围的这些磁场的强度不平衡,以产生差分 在其上的力并且将这些端中的一个按压到一个极靴的接触表面上,并且将另一端保持与另一个极靴相距一定距离。 磁性枢轴包括具有两端的部件。 它包括具有两个极片表面的引导装置,每个引导装置产生吸引这些端部之一的磁场,施加在两端的磁力具有不同的强度,以便仅吸引一端与这些极中的一个接触 零件表面。
