Surface Responses of Magnetic Fluid Adsorbed to Permanent Magnet Subject to Vertical Vibration
The surface responses of magnetic fluid adsorbed to a ferrite permanent magnet subject to vertical vibration were studied experimentally. It was found that pulsating capillary jets of magnetic fluid were produced at a certain excitation frequency. Large-amplitude azimuthal surface motions occurred when the fluid responded as a one-half subharmonic of the excitation.
