摘要：
The effect of thermal percolation in a magnetic fluid composite was found when changing the content of con-ducting microparticles in a low-conducting medium. It is shown that the effect of the magnetic field on the thermal conductivity of the composite material is significant at the concentration of conducting microparticles above the percolation threshold and much less pronounced otherwise. The relative increase in thermal con-ductivity can exceed 600% under the influence of a magnetic field parallel to the heat flux and is achieved in fields of intensity <10 kA/m at a volume concentration of conducting microparticles of 0.25.
