Abstract
A measuring method of contactless magnetic detection of relative movement along a trajectory between a main creation system and a measuring system sensitive to the direction of the magnetic field, the creation system creating a main magnetic field of direction that varies in a plane detected by the measuring system to determine the relative position along that trajectory. The method includes subjecting the measuring system to a compensation magnetic field of direction that is fixed and opposite to the direction of the maximum main magnetic field measured by the measuring system and delivered uniquely by the main creation system and in determining the direction of a magnetic field resulting from the combination of the main magnetic field and the compensation magnetic field by measuring the two mutually-orthogonal components of the resultant magnetic field respectively varying substantially as cosine and sine functions of the angle of the resultant magnetic field.
