Abstract
In this article, the processes of structuring non-magnetic microparticles of various shapes (spherical and cylindrical) placed in magnetic liquid are investigated. It was established that the equilibrium orientation of non-magnetic microparticles and structural formations from them in magnetic and electric fields is determined by the ratio of both field strengths and magnetic and electrical parameters of the carrier medium and material of non-magnetic inclusions. Analysis of mechanisms of interaction of non-magnetic filler particles and orientation of formed structures under the influence of magnetic and electric fields was carried out. It has been found that the action of a uniform magnetic field on a magnetic liquid with a dispersed non-magnetic filler leads to a significant anisotropy of the thermal conductivity coefficient - the difference in the thermal conductivity coefficient in the direction coinciding with the field strength vector and perpendicular to it can reach 25%. The analysis of the detected effect is made on the basis of ideas about the occurrence of structural anisotropy in such a medium due to the structural organization of non-magnetic filler particles in the magnetic field.
