Abstract
A multipolar magnetization device comprises at least one electric power source, at least two distinct current pulse generating devices and several portions of electric conductors respectively connected to at least four of said conductor portions for producing a given magnetic field portion. The magnetization device is arranged for creating a series of magnetic field portions of successive alternating polarities for producing in a magnetizable body a corresponding series of magnetized zones.
