A Force measurement device (10) is provided comprising a first magnetic field generating unit (160) configured to generate a magnetic field for being applied to a test object; a first magnetic field sensing unit (170) configured to sense the generated magnetic field; a flux concentrator (100) having a first pole (110), a second pole (120) and a third pole (130). The first pole, the second pole and the third pole extend in the same direction, wherein the first magnetic field generating unit is arranged at the first pole, wherein the first magnetic field sensing unit is arranged at the second pole, wherein an envelope (102) of a first end face (112) of the first pole, a second end face (122) of the second pole and a third end face (132) of the third pole is concave shaped. |
