磁性流体是一种具有强磁性的液状材料。系由磁铁矿(四氧化三铁)均匀地分散于诸如灯油、水及酯类等溶剂中,构成胶体状的分散液体。这种强磁性体粒子的大小为70～150埃。由于分散性好,不会发生由于重力或磁场而引起的沉降或凝聚等固-液分离的现象,而是一种具有强磁性的均匀
Magnetic fluid is a kind of liquid material with strong magnetism. Department by the magnetite (ferroferric oxide) evenly dispersed in such as lights, water and esters and other solvents, forming a colloidal dispersion liquid. The ferromagnetic particles have a size of 70 to 150 angstroms. Due to the good dispersibility, solid-liquid separation such as sedimentation or aggregation due to gravity or magnetic field does not occur, but a phenomenon of uniform ferromagnetism
