摘　　要：研究了磁性液体在平行于激光照射方向具有不同梯度的外磁场作用下,其光透射率随时间的变化情况,并从理论上定性分析导致出现这种现象的内在因素,以及磁性微粒在外加梯度磁场的作用下在磁性液体内部的微观运动情况.This article discusses the distribution of the magnetic field between two solenoids by experiment at first, and then the authors calculate the gradient of magnetic induction between two solenoids. This article introduces the transmission intensity of light through magnetic liquids under different magnetic fields which parallel to the light direction. The authors analyze the course of these phenomena and discuss how the magnetic nanoparticles move under different magnetic fields.

关 键 词：磁性液体 磁场 光透射率
