Abstract
Magnetic compound fluid is regarded as a mixture of magnetic fluid with particles of nanometer size and magneto-rheological fluid with particles of micron size. The magnetic rubber which is produced by mixing the magnetic compound fluid and a silicone rubber has strong saturation magnetization and small coercive force compared with magnet sheet. In this research, responses of the coupled system of the magnetic fluid layer and the magnetic elastic membrane to applied traveling magnetic field that is generated by 12 coils are investigated experimentally. It is shown that the wave on the magnetic elastic membrane is generated and propagated by applying traveling magnetic field. The amplitude of the wave is affected by frequency of applied magnetic field and depth of the magnetic fluid layer.
