Electric Current of Ferrofluid Depending on Temperature

Abstract:

Without external magnetic field, the relationship between electric current of ferrofluid (MF) and temperature is discussed. The electric current is increasing linearly with temperature rising in ferrofluid with Fe₃O₄ particles distributed into water (MF-Fe₃O₄-W). Through theory and experiment proved, the carrier liquid only in MF-Fe₃O₄-W could not decide the ability of delivering electric energy of MF-Fe₃O₄-W. The electric current would be contributed to the movement of free electric charges (or ions) and colliding of electric polarized particles in MF-Fe₃O₄-W.
