Investigating the Influence of the Magnetic Field on the Flow of Colloidal Fluid in a Microchannel System

The motion of ferromagnetic liquid entering the distilled water stream in the channels of the tesla micromixer M-4 configuration with a characteristic size of 400 mu m was investigated in this paper. The interface between two liquids in a magnetic field and without it was considered. The source of the magnetic fieldwas located on different sides relative to the feeding ferromagnetic liquid. It has been shown that when an object is located in a magnetic field, the solubility of the ferrofluid in the base liquid increases. Lambda significant part of the ferroparticles of colloidal liquid in small channels is attracted to the source of the magnetic field (up to 80%), which allows reasonably assuming that the use of ferroparticles for the transportation of medicines is promising.
