To reduce a hysteresis error, the invention provides a load measurement method (12) for measuring a load in a test object (14), comprising: a) generating a magnetic field in the test object (14) by means of at least one magnetic field generating coil (Lg) to which a periodically alternating current is applied; b) detecting a magnetic field parameter which changes on the basis of a load in the test object (14), using at least one magnetic field detecting device, in order to generate a magnetic field parameter signal (51) which changes periodically according to the periodically generated magnetic field, characterized by: c) detecting the hysteresis-to-signal ratio of the magnetic field parameter signal (51) over time within one period; and d) disregarding magnetic field parameter signal values from at least one predetermined timespan within each period in which a maximum hysteresis-to-signal ratio occurs.
