Claim 0:
1. A load measuring arrangement (16) comprising a test object (14) and a load measuring apparatus for measuring a load at the test object, wherein the load measuring apparatus (12) has a magnetic field generating device (18) for generating a magnetic field in a measuring region (11) of the test object (14) and a first and a second magnetic field capturing device (20, 22) for capturing a magnetic field parameter which changes on account of the load,
wherein the measuring region (11) has a layer (13) made of a ferromagnetic metal with a maximum particle size less than 1 μm,
wherein the test object (14) includes a body (48) made of a non-ferromagnetic material or made of a ferromagnetic material with an electrically conducting non-ferromagnetic separating layer, and the layer (13) made of the ferromagnetic metal is coated thereon at least in the measuring region (11), and
wherein the ferromagnetic metal includes one or more selected from the group consisting of electroless nickel, and a metal alloy including electroless nickel and phosphorus.
