Abstract
Dynamic behaviors of magnetic fluid adsorbed on the permanent magnet subject to vertical vibration or alternating magnetic field were examined with a high speed video camera system. In the experiments, the electrodynamic shaker was used to produce the vertical vibration, and the Helmholtz coil was used to generate the alternating magnetic field. The generation process of capillary jets and droplets of magnetic fluid was observed. It was confirmed that capillary jets of magnetic fluid can be produced both by the vertical vibration and by the alternating magnetic field. The dynamic characteristics of magnetic fluid surface to the vibrations were revealed experimentally.
