Abstract
The article presents results of an experimental study of capturing, transporting and subsequent splitting of an air cavity into bubbles by a magnetic fluid in the zone of `magnetic vacuum' of an annular magnet. The study was carried out using the acoustomagnetic method. The captured air cavity is characterized by a decreased elasticity coefficient, and the resulting bubbles are relatively large in size. Figs 8, Refs 20.
