磁流体表观密度与外磁场间变化规律研究(英文)

Research on Corresponding Variation between Apparent Density of Magnetic Fluid and Its Applied Magnetic Field

研究了磁流体表观密度与外磁场间的变化规律。采用流体静力称衡法对自行研制的煤油基磁流体进行测量,得到了如下结论:在磁流体中非磁性物体的质量与外磁场成反比,表观密度与外加磁场成正比。

This paper report the corresponding variation between the apparent density of magnetic fluid and its applied magnetic field. By using hydrostatic measurement in the self-made kerosene base magnetic fluid, a conclusion can be obtained as follows: the non-magnetic object's mass in the magnetic fluid is inversely proportional to the applied magnetic field; while the apparent density of magnetic fluid is directly proportional to it.
