Magnetorheological materials (MR fluids) are a class of smart materials whose rheological properties (e.g. viscosity) may be rapidly varied by applying a magnetic field. Under influence of magnetic field the suspended magnetic particles interact to form a structure that resists shear deformation or flow. This process takes only a few (1–10 ms) and magnetorheological fluid rapidly changes its viscosity.

The main aim of this article was to present the investigation results of magnetorheological fluids (MR) composed of carbonyl iron (CI) particles and analyse their flow behaviour in terms of the internal structure formation by a control of applied external magnetic field. The paper presents also the results of the experimental studies of a prototype magnetorheological damper at various magnitudes of control current as well as the manner of modelling electromagnetic phenomena occurring in the damper are presented in this paper.

The researches were carried out on model MR fluid which was prepared using silicone oil OKS 1050 mixed with carbonyl iron powder CI.
