摘要
铁磁流体是一种由大小为１０ｎｍ的固态磁性微粒，它是通过表面吸附活性剂均匀分散于载体中形成的超稳定性的胶体悬浮液．在外加磁场作用下，磁流体的粘度随磁场强度的变化而变化．本文作者通过自行研制的旋转式、落柱式和细管式磁流体粘度计，对铁磁流体在磁场作用下的粘度变化进行了测量研究．
Ferromagnetic liquids,or the magnetic liquids,are ultrastable colloidal suspensions of submicrosized(1～10nm)magnetic particles in certain carrier liquids with the dispersing agent added to prevent flocculation.The viscosities of these liquids vary with the applied magnetic field.In this study,variations of viscosity with the applied magnetic field for some ferromagnetic liquids are measured using three kinds of viscosimeters developed by the authors.
