Abstract
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.
