Abstract
In order to form, on opposite plane surfaces of a magnetizable plate portion of a part (62), a series of magnetized areas, the device comprises a frame (68) wherein two support parts (64, 65) made of a material having a high magnetic permeability presenting respectively plane polar surfaces are arranged in parallel facing each other and are coupled with portions of electric conductors arranged so as to generate between the polar surfaces of the opposite support parts magnetic field producing the magnetization of said areas. One of the support parts (65) is displaceable with respect to the other one (64) and with respect to the frame (68), perpendicularly to the polar surfaces so as to bring close and to spread apart said polar surfaces with respect to the flat portion of the parts to be magnetized.
