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.

A pressing tooling machine, including one or two punches, a die including sectors that can separate from each other but are connected to a shared primary portion, and a ring surrounding and holding the sectors, against which it is adjusted by tapered surfaces, and the altitude of which varies owing to the rotation of a crown provided with a surface in relief. When compression is finished, stripping is preceded by a slight separation of the sectors, which makes it possible to release stresses in the compressed piece and avoid many risks of damaging the piece. The sectors are made resistant by inserts made from a hard material, generally removable and able to be machined to an exact profile of the pieces to the formed.
