Title (EN) METHOD OF MANUFACTURING A DEVICE
(FR) PROCEDE DE FABRICATION D'UN DISPOSITIF
Abstract:
(EN) An element of an apparatus is magnetized so as to generate a magnetic field pattern around the element. To achieve this, use is made of a magnetizing coil, and the element and the magnetizing coil are moved relative to each other, the magnetizing coil carrying an alternating current of substantially constant amplitude as well as a signal current. Preferably, there is a phase difference between the signal current and an intended magnetic field pattern.
(FR) L'invention concerne l'aimantation d'un élément d'appareil pour générer un champ magnétique autour de l'élément. Pour obtenir ce résultat, on utilise une bobine d'aimantation, et l'élément et la bobine d'aimantation sont déplacés l'un par rapport à l'autre, la bobine d'aimantation portant un courant alternatif d'amplitude sensiblement constante ainsi qu'un courant de signal. De préférence, il existe une différence de phase entre le courant de signal et une configuration de champ magnétique voulue.
