Experimental investigation of surface instability of a thin layer of a magnetic fluid

In the present work the instability of a flat horizontal thin layer of a magnetic fluid (the depth of no more than 50 μm) under the action of a uniform magnetic field is studied experimentally. It was revealed that the development of instability under the action of tilted magnetic field can lead to...
