Abstract: A sensor system having a permanent magnet for a sensor for determining a relative angular position (?(t)), whose magnetization vector (M(P)) at a point (P) presents, in orthogonal projection on a plane perpendicular to its main axis (A?), a projected vector whose relative orientation (?rp(?(P))) with respect to the particular radial segment (SRP) at this point (P) is a continuously variable function of the angular position (?(P)) of the point (P), periodic function having an even integer (Np) greater than or equal to 2 of angular periods (T) over the 360° about the main axis (A?), with a positive variation of the relative orientation (?rp(?(P))) as a function of a positive variation of the angular position (?(P)) of the point (P); a method implementing such a sensor system; and a method for manufacturing a magnetized body.

Abstract: A method for determining an angular position between two parts having a magnetized body cylindrical of revolution and with a diametrical magnetization; and two measurement cells in positions spaced by a non-zero fixed angle strictly less than a 90 degree angle about the axis of rotation. The method includes arranging the two measurement cells on the second part such that their primary measurement axes are parallel to each other, and that their secondary measurement axes are parallel to each other; and determining a value representative of the relative angular position as a function of a ratio between the difference of the secondary components and the difference of the primary components, measured by the two cells.
