Thermo-physical properties of magnetic fluid (MSG-W11) were elucidated in order to examine its temperature dependency under magnetic field. Heat transfer by natural convection was also investigated in a horizontal enclosed rectangular container filled with the magnetic fluid which was heated at the lower surface and cooled at the upper surface under magnetic field. Various thermal properties of the magnetic fluid and their temperature dependency were clarified in the present research. It was also found that the heat transfer coefficient coincides well with the conventional heat-transfer correlation of natural convection heat transfer in a horizontal enclosed rectangular container by applying the values of thermo-physical property obtained in the present research.
