In the present paper, the dynamic behavior of magnetic fluid surfaces in containers were experimentally examined. Experiments were carried out for rectangular, cylindrical and spherical containers. These containers were horizontally oscillated. The vertical nonuniform magnetic field was applied by permanent magnets which were set underneath the containers. The test liquid was a magnetic fluid with fine magnetite particles in a water carrier. It was found that the harmonic wave motion, swirling waves and flow pattern of surface waves were influenced by the magnetic fields. The resonant frequency of the liquid-container system moved toward the high-frequency region with increase of the magnetic field intensity. This behavior was also studied by the linear theory. Theoretical results were qualitatively in good agreement with experimental results.
