A ferrofluid is the colloidal suspension of very fine magnetitie particles dispersed in a suitable liquid carrier. The presence of magnetic nanoparticles has been shown to provide both thermal and dielectric improvement to the power transformers. These polarizable particles, which are of higher permittivity than the surrounding liquid, experience an electrical force directed towards the place of maximum stress. In this study, we observed the behavior of magnetic nanoparticles to applied electric field (up to 2.5kV) in a microchannel by an optical microscope. We found that magnetic nanoparticles are equally dispersed in case of non-applied electric field, and those move into the region toward electrodes when the electric is applied. Therefore, it was concluded that the movement of magnetic nanoparticles is caused by the electric field, and the breakdown voltage of insulation oils including magnetic nanoparticles might be influenced positively or negatively.
