Journal de Physique et le Radium, 1950 L'étude porte sur le phénomène inverse de la magnétostriction dans le cas particulier de la contrainte mécanique de traction simple. Les variations de la perméabilité magnétique sont mises en évidence par la variation correspondante de l'inductance d'un solénoïde entourant une éprouvette en acier et alimenté par un courant sinusoïdal de fréquence et ...
