Abstract

Circuit magnétique en ferrite pourvu d'un entrefer et d'une possibilité de réglage de la valeur effective de cet entrefer. Selon l'invention, au moins l'un, 2, des deux demis-pots 1 et 2 présente au voisinage de l'entrefer 4 une paroi mince 5 dont le percement 7 graduel et partiel augmente la valeur de la réluctance dudit circuit. Ce circuit sera avantageusement utilisé dans la fabrication des matériels de télécommunication.
