The invention relates to a magnetic force sensor (100), having at least one conducting track (111, 211) of soft magnetic material, wherein the at least one conducting track (111, 211) has at least one interruption (130) having a distance (A), wherein the force sensor (100) is arranged on a substrate, in particular on a component (1, 2) to be monitored, and a change in the distance (A) or rather a change in the magnetic flux in the at least one magnetic conducting track (111, 211) is monitored.
