We have studied dielectric properties (complex permittivity and dielectric loss factor) of a transformer oil ITO 100 based magnetic fluid with various concentrations of magnetic Fe3O4 nanoparticles covered with oleic acid as a surfactant. The experiments were carried out at different volume concentrations of magnetite nanoparticles up to 4
