“…The buoyancy principle and the controlled flow are the two attractive characteristics of magnetic fluid. The buoyancy of magnetic fluid could be used in mining industry and substance flotation [1][2], damping [3], bearing [4] and the design of new sensors [5]. In this paper, the motion equation of acceleration sensor on slant was analyzed.…”

Acceleration sensor with magnetic fluid is a novel application of buoyancy principle of magnetic fluid. The model of the sensor was established in the paper. To improve the design of the acceleration sensor with magnetic fluid, motion equation of the sensor was deduced, which is the second-order vibration equation. From the equation, the damping coefficient is determined by magnetic viscosity coefficient of the liquid and the sensor structural parameters.

“…The Buoyancy principle of the magnetic fluid is one of the most attractive principles of the magnetic fluid statics. We can use the principle for different material separating in mining and metallurgical industries [1][2][3]. Moreover, new type sensors [4], dampers [5]and bearings [6] of magnetic fluid also can be designed with this principle.…”

The buoyancy principle of magnetic fluid is one of the most attractive effects of magnetic fluid statics. But it is too difficult to calculate the buoyancy directly due to the complexity of magnetic field. Moreover, numerical calculation employs too many assumptions. So in this paper the experimental method is adopted to measure the second-order buoyancy received by permanent magnet immersed in magnetic fluid, which depends on the distance between the magnet and the wall of vessel. The influence of the diameter of cylindrical vessels, the size of magnets and the saturation magnetization of magnetic fluid on the buoyancy is also analyzed qualitatively.

“…Theoretical research and experimental study have to solve the many problems relating micro-scale to macro-scale hydrodynamics. Based on the buoyant force in a MF, Murariu, Rotariu, Badescu, and Badescu (2001) solved the equations of motion of particles entering cells through a well-delimited surface. By studying the trajectories of particles, the possibility of efficient separation of particles with different densities was proved.…”
