Abstract
The dynamic behaviors of the two layers fluid in a laterally oscillating rectangular container under a vertical magnetic field were studied. The two layers fluid was a water-based magnetic fluid and a silicone oil. The frequency responses of displacement of free surface and interface were measured and their resonant frequencies moved to higher frequencies as the magnetic field intensity was increased. The velocity profiles in magnetic fluid and silicone oil were periodically measured during a sloshing cycle by using the ultrasound velocity profile system(UVP).
