Abstract: The problem of the dynamics of a material point that interacts with some linear wave field in a finite neighborhood of the particle is formulated. It is shown that the emission of waves resulting from vibrations of the point (under the influence of the external force) can additionally lead to an acceleration of the point. The model is used to investigate the magnetoelastic dynamics of a ferromagnetic domain wall.
