Abstract:
Cyclic motion of a ferromagnetic part in an environment made noisy by at least one electric source with an A.C. component is measured using at least one first magnetometer sensitive to the moving part and a sensor of an image of current in the electric source. An estimate is calculated of noise linked to the electric source on a signal measured by the first magnetometer and then subtracted from the measured signal.
