Abstract
Dispositif à débosseler. Le dispositif comprend une première source de courant fournissant une première impulsion, une seconde source de courant fournissant une seconde impulsion de polarité opposée à celle de la première impulsion et de temps de montee plus court, une bobine électrique conformée pour délimiter une zone prédéterminée de contrainte fournissant un flux électromagnétique localisé. Débosselage de matières conductrices.
