Abstract

The problem of the forces acting on the permanent magnet placed in a rectangular cavity filled concentrated magnetic fluid, was solved in two dimensions. The problem is solved with regard magnetophoresis and diffusion of particles, demagnetizing fields and interparticle interactions. The demagnetizing field and the concentration of colloidal particles were calculated. The dependencies of the resultant force from magnet position and value of the interparticle interactions parameter were found. A strong magnetophoresis and interparticle interactions influence on the equilibrium position of the magnet in the cavity were demonstrated.Received 22.10.2016; accepted 05.11.2016
