The assembled measurement body in a measurement direction (X) has alternately a magnet element (43, 44, 53) of the first basic body (40) and of the second basic body (50). The magnetisation of the magnet elements (43, 44) of one basic body in an assembled condition, is aligned opposite to the magnetic field of the magnet elements (53) of the second basic body. The two basic bodies have at least approximately the same dimensions, and when jointed together, in the gaps of the raised magnet elements (43, 44) of one of the basic bodies, engage the raised magnet element of the other basic body. The two basic bodies are joined together by adhesive.
