Abstract

Magnetorheological (MR) fluids are basically suspensions of magnetically particles immersed in a nonmagnetic fluid. MR fluids change their rheological properties when an external magnetic field is applied. Many studies have focused on the optical response of MR fluids to unidirectional magnetic fields. The application of optical trapping techniques in MR fluids is to measure the mechanical properties of single dipolar chains, such as the rupturing tensions and strains under tensile and lateral deformations. However, their inner structure by method of visualization and image processing when an external magnetic field is applied has been a new research area of interest. This paper would be elaborate experiment result of inner structure of MR fluid by means of visualization using optical microscope and CCD camera. The results show the rate of cluster formation is increase when the strength of magnetic field is increase, means that cluster formations are more robust and larger size for high magnetic field. The investigation of inner structure of MR fluids using image processing was successful. The growth of cluster formation is clearly seen in our image analysis. The cluster develops more robust when the magnetic field intensity is increase.
