【 摘 要 】

In this paper, the relationship between the magneto-viscous properties of magnetic fluids and the sensitivity of inductive horizontal sensors based on magnetic fluids is studied experimentally. The experimental model of magnetic fluid horizontal sensor is established. The magnetic viscous properties of kerosene-based magnetic fluids were prepared and analyzed. The experimental results show that the magnetic fluid with saturation magnetization between 310 Gs and 425 Gs is suitable for the magnetic fluid horizontal sensor. The sensitivity of the sensor is proportional to the magnetization coefficient of the magnetic fluid. On the premise that the magnetic fluid has good fluidity, the sensitivity of the sensor can be increased by increasing the magnetization coefficient of the magnetic fluid.
