Аннотация

The flow of a thin layer of a magnetic fluid along a horizontal plane near an fixed magnetizable cylindrical body in an applied uniform vertical magnetic field were investigated theoretically and experimentally. The shapes of the surface of the magnetic fluid at different times were plotted. The influence of the applied field on the flow of the layer was studied.
