摘要：
This paper studies how a spherical magnetizable body interacts with a magnetic fluid layer on a horizontal plane in a uniform vertical magnetic field. It is experimentally shown that the body can move along the magnetic fluid layer. A theoretical analysis takes into account gravity and viscous friction. The impact of the problem parameters on the magnetic force acting on the body from the layer is investigated, and it is shown that the body can be either attracted or repelled by the magnetic fluid layer.
