Abstract
Senseur pour mesure de la variation d'un flux magnétique. Il comporte un premier générateur de champ magnétique constant et un générateur de HalL Un objet influençant le champ magnétique est disposé de telle sorte que le champ créé par le premier dispositif est dirigé vers l'objet et en revient. Le premier générateur crée un second champ magnétique qui ne traverse pas l'objet et dans lequel est placé le générateur de Hall. Application à la métrologie.
