The invention relates to a probe for analysing an assembly of rods including an elongate housing (1) supporting at a first end a permanent magnet (5), the north-south axis of which is parallel to the axis of the rods and, in a position sufficiently separated from said magnet, a set of magnetometers (7) for detecting axial, radial and tangential components of the magnetisation of the rods. |
