The effect of magnetophoresis and Brownian diffusion on the levitation of bodies in a magnetic fluid

New aspects related to the redistribution of magnetic particles concentration in a magnetic fluid caused by magnetophoresis and Brownian diffusion in a nonuniform magnetic field are considered. These aspects deal with the influence of these processes on pressure redistribution and levitation of bodies in a magnetic fluid. It is shown that due to these processes the pressure force acting on bodies changes significantly with time and can be reduced dozens of percent if compared to a homogenous flui

Influence of Brownian diffusion on the statics of magnetic fluid

In the present study, the influence of Brownian diffusion of magnetic particles in a magnetic fluid on a force, which acts upon a fluid volume under an external inhomogeneous magnetic field to be induced by a pair of flat poles, is considered in plane geometry. It is shown that the re-distribution of magnetic particle concentration causes this force to undergo considerable changes with tim
