1. An arrangement for measuring a mechanical load on a test object, with the detection of changes in the magnet field, comprising:
a test object (14) extending in its longitudinal direction L;
at least one sensor element (18) comprising a magnetic field generation device (20) for generating a magnetic field in the test object (14) and a magnetic field detection device (22) for measuring a change in the magnetic field in the test object (14); and
a device for compensating for a signal variation that occurs when the test object (14) is rotated,
wherein the sensor element (18) is arranged on a measurement surface (15) of the test object (14) which extends with at least one directional component radially and/or transversely to the longitudinal direction L of the test object (14).
