3 磁性液体的基本特性磁性液体的特性是磁性颗粒、界面活性剂及载液性能的综合表征。作为一种特殊的胶体体系 ,磁性液体同时兼有软磁性和流动性 ,因此它具有特殊的物理特性、化学特性及流体特性。3 .1 特殊的物理特性3 .1 .1 磁化特性磁性液体中的磁性颗粒平均为十几个纳米
3 the basic characteristics of the magnetic fluid The characteristics of the magnetic fluid magnetic particles, surfactant and carrier fluid performance of a comprehensive characterization. As a special colloidal system, the magnetic fluid has both soft magnetic properties and fluidity, so it has special physical, chemical and fluid properties. 3.1 Special Physical Properties 3.1.1 Magnetizing Properties The average number of magnetic particles in a magnetic fluid is a few dozen nanometers
