【摘要】 本文利用自制煤油基磁流体。采用流体静力称衡法对磁性流体（简称磁流体） “表观密度”在非均匀磁场中的变化规律进行了研究，实验结果表明磁流体“表观密度”与磁场梯度的大小有关。更多还原

【Abstract】 The corresponding variation of the apparent density of magnetic fluid in non-homogeneous magnetic field was studied with self-made kerosene base and hydrostatic measurement. The experimental result shows that the apparent density of magnetic fluid varies with the gradient of the magnetic field.更多还原
