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.
