| Abstract: | The magnetic fluid was prepared using the Dysprosium Ferrite particulates prepared by chemical precipitation and suspended in a carrier liquid. The influence of operating temperature, dosage of Dysprosium, pH, and surfactant on the stability of the magnetic fluids were studied . The factors influencing the magnetic intensity of saturated Dysprosium Ferrite magnetic fluid was determined. A theoretic analysis was given. |
