Paper presents the new methodology of application of uniform torque to the ring-shaped magnetoelastic sensing elements. The results of investigation on the influence of a torsion on the magnetic properties of different amorphous Fe-based ring cores are also presented. The results of tests on Fe Si B amorphous alloy in as-cast and annealed state as well as Fe Nb Cu Si B nanocrystalline alloy indicate, that torque sensitivity is connected with both alloy composition and state on the alloy. Moreover the most sensitive is F amorphous alloy in annealed state. As a result this alloy is the most suitable as a core of magnetoelastic torque sensors.
