Load measuring arrangement, method for producing said arrangement and load measuring method which can be carried out with said arrangement

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.
