The paper presents experimental materials obtained in studying the ferromagnets behavior exposed to dynamic deformation. The study made it possible to use transducers structurally similar to the magnetoelastic ones to measure the dynamic loads. Discovery of a new physical effect consisting in generation of the additional EMF in the magnetoelastic converter winding at dynamic deformation of its magnetic circuit was experimentally confirmed. Studying the ferromagnet behavior exposed to dynamic deformation, as well as the ferromagnet dynamic stabilization modes, made it possible to clarify the reason that previously did not allow using the magnetoelastic type transducers in measuring dynamic and also the shock loads, as well as to propose an approach to solve this problem.
