Abstract

This paper describes a methodology developed by Eletrobras Cepel Laboratories for electromagnetic characterization of Magnetic Nanofluid (MNF). The magnetic nanofluid was obtained from addition of magnetite nanoparticles in mineral insulating oil in various concentrations. Electrical and magnetic properties of the MNF were measured as a function of temperature, frequency and nanoparticles concentration. The results are presented and discussed, showing the effectiveness of the proposed characterization methodology, as well as the promising results on electric insulation properties of the MNF.
