The results of an experimental study of magnetic liquid surface responses in a container subject to magnetic field and vibrating field were presented and discussed in detail. Experiments were performed on a vibration-testing system which provided lateral and longitudinal excitation. The effect of the magnetic field gradient on liquid surface motion in an open circular cylindrical tank was noted. Data obtained for the cylindrical tank were also compared with numerical results based on the linearized theory. Nonlinear phenomena were found for the symmetric free surface mode (0,1) in longitudinal liquid sloshing. Details of surface responses of a magnetic fluid in the cylindrical tank excited longitudinally under an applied magnetic field were revealed. Some similarities and differences between single spike oscillation and the symmetric free surface mode (0,1) of magnetic liquid sloshing in the presence of a magnetic field were also investigated.
