  • Abstract
    The sound velocity in a magnetorheological fluid under the influence of magnetic fields is empirically studied in this work. The effect of changing the magnetic field both in geometry, intensity and uniformity using permanent magnets placed in different configurations is analyzed. It is shown that the acoustical properties of the fluid can be easily changed tuning them at our discretion.
