Abstract
The results of studies under electro-mechanical action for structure elements of disperse objects and living organisms are shown. On the example of the cavitation magnetohydrodynamic resonator model, an opinion was expressed what is unity of common approaches at formation of electro-mechanical action in heterogeneous systems in point of boundary of the transition from component to another component. It is shown that the addition of the mechanical nature of the oscillations to the electromagnetic action contributes to the appearance of resonant phenomena in the heterogeneous system. This, in principle, can lead to the destruction of the shells and coats of machine components, mechanisms or to change of the state in material or living object.
