| Abstract: | The magnetic fluid was prepared using the ultrafine Co-Fe 3O 4 particulate as the group material. The influence of the radius of magnetic fine particulate and the surfactant upon the magnetic performance of the fluid was investigated respectively, the preparation condition was optimized using the orthogonal experiment, and the magnetic intensity of the fluid was tested. The result indicated that the magnetic performance of Co-Fe 3O 4 magnetic fluid mainly depended upon the radius and content of magnetic fine particulate and the content of the surfactant. |
