The impact of electromagnetic radiation on the dielectric properties of magnetic nanofluids

Abstract

Presented article discusses the impact of electromagnetic radiation on dielectric properties of magnetic fluids based on transformer oil ITO 100. For measurements and evaluation of the samples we used the PDC analysis. The measurements were performed in two variants, specifically when individual samples were irradiated and were not irradiated with the external magnetic field. To minimize undesired electromagnetic fields, the measurements were realized in the anechoic EMC chamber. The main objective of this experiment was to determine if the electromagnetic radiation can change properties of magnetic liquid. Used samples of magnetic fluids were with different concentrations of magnetic nanoparticles. In the experiment was generated electromagnetic field, used to charge and discharge streams, of which are indicative of the state of the insulation system. For comparison of the results the samples were analyzed before irradiation with EM field and after irradiation with EM field.
