The rotation and translational motion of the samples with a magnetizable material alonga bottom of a vessel in a uniform applied rotating magnetic field are examined experimentally. Weconsider a magnetic fluid (MF) drop and a body with a magnetizable polymer (MP). The phenomenaof the change of the direction of the translation motion at some field frequency is observed only forthe MF drop.

We consider a heavy, incompressible, homogenous, isothermal magnetic fluid between two coaxial cylinders in case of wetting. There is a current-carrying straight wire on the axis of these cylinders. The magnetic fluid is immersed in a non-magnetic liquid with the same density (the case of hydroimponderability). We apply the Langevin law to describe a magnetic fluid magnetization. Using the general analytical solution for any axially symmetric shape of the magnetic fluid free surface in any axisymmetric magnetic field, we investigate the break-up and the rebuilding of the magnetic fluid bridge in case of wetting.
