Abstract
An electromagnetic device includes a conductive coil, a main magnet pivoting about an axis XX′, a first and second yoke, a first and second stabilizer magnet, as well as a first and second actuator magnet arranged to slide along the axis YY′ that is perpendicular to the pivot axis XX′, in such a way as to force the main magnet to adopt an equilibrium position, the stabilizer magnets are arranged such that this sliding is accompanied by a movement of the stabilizer magnets so as to position one of the stabilizer magnets in a given position in order to limit the leaks which could occur at one of the two yokes.
