Abstract
The invention concerns a magneto-resistive magnetic sensor comprising a magneto-resistive element, the resistance of which varies as a function of the applied magnetic field and two pole pieces that collect the magnetic field to be detected so as to concentrate it in the magneto-resistive element, each pole piece being positioned to partially overlap the magneto-resistive element, a current I passing through this magneto-resistive element, wherein the zones of the magneto-resistive element that are overlapped by pole pieces are cut out such that the current that passes through the magneto-resistive element is located in a zone in the air gap between the two pole pieces.
