磁性液体既具有普通液体的性能，又有超顺磁性。分析了磁性液体的磁化机理，测量了磁性液体的磁化曲线，并对工作磁场中的磁性液体的磁化曲线进行了拟合。将磁性液体用于传感器研究，通过计算得出传感器的灵敏度与磁性液体的磁导率之间的关系，并设计相应实验，通过实验得出结论：传感器的灵敏度随着磁性液体磁化强度的增强而逐渐增大，但是在磁性液体磁化强度增大的同时，密度也会增大，从而造成随着磁化强度的增强，传感器灵敏度增长逐渐迟缓。

Magnetic fluid has both the properties of common fluid and superparamagnetism.The magnetization mecha-nism of magnetic fluid was analyzed, the magnetization curve was measured, and then the magnetization curve of mag-netic fluid in the magnetic field was fitted.Magnetic fluid was applied to the study of sensors and the relationship be-tween the sensitivity of the sensor and the magnetic permeability of magnetic fluid was calculated.Proper experiments were designed and conducted.And the conclusion was drawn that the sensitivity of the sensor increased gradually with the enhancement of the magnetization of magnetic fluid.However, in the meantime, the density of magnetic fluid also increased with the enhancement of the magnetization of magnetic fluid so that the sensitivity of the sensor grew rather slowly.
