Abstract

L'invention est relative à un noyau magnétique réalisé dans un alliage fer/nickel, comportant des additifs de traitement et de désoxydation, tels le silicium et le manganèse, pour l'application des impulsions à l'aide d'une course d'induction supérieure à 1 Tesla et une grande perméabilité aux impulsions, caractérisé en ce que l'alliage qui renferme entre 49 et 56 % en poids de nickel est, successivement et dans l'ordre, laminé en bandes minces, d'une épaisseur maximale de 0,1 mm, transformé en noyau magnétique, recuit pendant une durée de 3 à 6 heures sous atmosphère d'hydrogene et à une température supérieure à 1 000 degrés C, refroidi à la température ambiante, chauffé à nouveau et porté à une température supérieure au point Curie, pour être finalement refroidi dans un champ magnétique dont les lignes de champ évoluent transversalement au sens du flux magnétique futur.
