Abstract

L'invention a pour objet une sonde de mesure de susceptibilité magnétique. Cette sonde est du genre de celles qui comprennent deux enroulements inducteurs de même axe montés en opposition et reliés à un générateur de courant alternatif et un enroulement de mesure situé entre les deux enroulements inducteurs et d'axe perpendiculaire à l'axe de ces derniers. La sonde est caractérisée en ce qu'elle comprend en outre un enroulement de compensation coaxial à l'enroulement de mesure et disposé symétriquement de celui-ci par rapport à l'axe des enroulements inducteurs. Application à la mesure de la susceptibilité magnétique des terrains.
