“…In modern literature the manifestations of several different capillary, hydrostatic, electro-and magnetostatic instabilities that take place at the interface of magnetic colloid (magnetic fluid) with other media under the influence of external force fields are known and intensively studied [1][2][3][4][5][6][7][8][9]. In the development of physics of magnetic colloids, much attention is traditionally paid to the problems of equilibrium shapes of their limited volumes determined by the action of magnetic interaction forces and surface tension.…”

This paper presents experimental studies of the influence of an alternating magnetic field on the separation of magnetic liquid droplets from a capillary hole. The formation of waves on the surface of capillary volumes of a magnetic fluid flowing out of a capillary hole in a horizontal non-magnetic plate under the action of gravity in external alternating magnetic field is detected. Spherical, dumbbell-shaped, jet-shaped, and comb-shaped droplet geometries were observed. It is established that the shape of the waves formed could vary from waves running and standing on the surface of a growing drop to bending oscillations of a vertical fluid jet. The magnetic field parameters at which different instability patterns are observed were determined.
