Although there is no general association of OAM with vortices, for familiar wave fields with circular symmetry this association has some validity and vortex beams are usually referred as such. Besides optical vortex beams which are widely used in numerous technical instruments such as tweezers, separators, etc., the area of electron vortex beams (EVB) have undergone a considerable progress in last few years. Several directions of research are under way. Since their theoretical prediction and first experimental creation the theory of behavior of such beams in various situations was developed: dynamic, inelastic and Rutherford scattering, interaction with light and interaction with crystals. It was however the interaction with a magnetic field which was of particular interest and where several interesting phenomena occur. The second direction of research is focused on potential applications which are the aim of this presentation. Even though the conventional ready-to-use application is not available yet, there are some promising signs such as contrast enhancement, probing magnetic plasmons, crystals chirality determination, electron magnetic circular dichroism (EMCD) or spin-polarized transitions mapping.
