磁性液体的磁性对传感器灵敏度的影响研究
Research on the Impact of Magnetism of Magnetic Fluid on the Sensor Sensitivity
摘要
Abstract
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.关键词
