Effect of an applied magnetic field on sloshing pressure in a magnetic fluid

Sloshing of a magnetic fluid can be controlled through altering the sloshing natural frequency by applying magnetic fields. The magnetic field is applied by two permanent magnets. The intensity of the applied magnetic field is changed by varying the position of the magnets and the magnet type. The dynamic pressure responses on the inner wall surface were used to gain an understanding of the sloshing phenomenon in this investigation. Several frequency response spectra are obtained in each experimental condition. These results indicated that the free surface disturbance caused by the sloshing was suppressed by the applied magnetic field.
