The invention also relates to a magnetic device for detecting a torque between a first shaft and a second shaft that are connected via a torsion bar. The aim of the invention is to provide a device for determining the multi-periodic absolute position of a magnetized unit.

The second magnetosensitive probe (3) is capable of measuring a number of complete rotations of the magnetic field in an absolute, incremental and reversible manner so as to determine a second datum relating to the position of the magnet (1), whether or not this second magnetosensitive probe (3) is powered. The sensor further includes a module for calculating the absolute position of the magnet (1) on the basis of the first and second data coming from the first and second probes (2, 3) respectively.
