A force transducer element (20) comprises a body (22) of magnetisable material having at least one magnetised region (30) at an angle, say 45null, to the force-sensing direction (P-P). Preferably there are a plurality of parallel magnetised regions of alternating opposite polarity of magnetisation to form closed loops (43p, 43n). The element may be a block having opposite force receiving surfaces (24, 24null). The body (122) may contain plural transducer elements (120a, 120b) angled to one another to resolve force directions. The principle is extended to a circular transducer element (243). The invention may be implemented in a flexible magnetic tape. Another embodiment (300) is realised in a planar structure in which a ferromagnetic core (310) is subject to a magnetic field (326) at an angle to the direction (F) of force application generated by laterally offset coils (312, 314). A sensor device (330) is fabricated in the structure.
