The research of the conductive mechanism and properties of magnetorheological fluids

We investigated the resistance response induced by the magnetic field in magnetorheological fluids, the resulting magnetization process alters the distribution of the ferromagnetic particles from unordered distribution to catenulate distribution. Consequently the electrical conductive property of the whole sample changes. A four-stage model has been built to describe the distinct characteristics of the variation of the magnetorheological fluids resistance with a sectional formalism, which is found in excellent agreement with the experimental results. Also, the application of the electrical properties of the magnetorheological fluids in the engineering field is discussed. (C) 2013 Elsevier B.V. All rights reserved.
