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。
The variation law between the apparent density of magnetic fluid and the external magnetic field was studied. The hydrostatic weighing method was used to measure the kerosene-based magnetic fluid developed by ourselves. The conclusions are as follows: The mass of the non-magnetic object in the magnetic fluid is inversely proportional to the external magnetic field, and the apparent density is proportional to the applied magnetic field.
