Abstract

A magnetic sensor of rotary, linear, or curvilinear displacement using at least one permanent magnet and at least one magnetosensitive element, which can move with respect to one another. The magnet exhibits a direction of magnetization that varies continuously along the direction of displacement, with the exclusion of a diametral magnetization in the case of a rotary sensor.
