Abstract

Abstract: Magnetic fluid is a liquid magnetic material with high magnetization, fluidity and superparamagnetism. The composition and the performance of magnetic fluid in magnetic field were introduced. Magnetic model of magnetic fluid for application was established. Magnetic particles could be seen as magnetic needles with certain N-S directions whose direction could be controlled by external magnetic field. Magnetization mechanism of magnetic fluid was researched. Measurement principle of magnetization intensity was studied and the formulas were deduced. The working principle of vibrating sample magnetometer was introduced and the magnetization curve of magnetic fluid was measured and plotted. It was concluded that magnetic fluid has superparamagnetism which means that the remanence and coercivity of aggregation of magnetic fluid are both zero. Magnetism is an important characteristic of magnetic fluid for engineering applications that magnetic fluid with high magnetization intensity will be explored and researched.
