Abstract

Noyau magnétique en deux pièces en forme de E comportant un entrefer qui s'étend sur toute la section droite entre les branches médianes opposées. Selon l'invention, il est prévu, dans l'une au moins des deux branches médianes formant entre elles l'entrefer, sur la face polaire de cette branche, un évidement s'étendant sur une partie de cette face polaire.
