Resumo

The shape of the free surface of a magnetic fluid, which it takes in an external homogeneous magnetic field near solid magnetic bodies, is experimentally investigated. The shape of the magnetic fluid surface in the vicinity of bodies of different basic geometry: cylinder, ball, plate is studied. The pattern of the magnetic fluid surface under the influence of a stationary and alternating magnetic field is considered. It is shown that the shape of the surface essentially depends on the volume of the magnetic fluid, the geometry of the magnetic body and the magnitude of the magnetic field. The obtained results indicate the possibility of purposeful control of the shape of the free surface of magnetic fluid, which may have practical applications.
