Abstract
A differential magnetometer consisting of at least one active coil () and a receiver coil () for which the windings are installed differentially, is provided with a measurement circuit () with a slaving device that corrects dissymmetry appearing between windings () to eliminate residual induction at the frequency of the magnetic excitation field, intended to make the measurement coil () more sensitive without applying a voltage to it.
