Kopcansky P., Tomasovicova N., Koneracka M., Zavisova V., Timko M., Tomco L., Dzarova A., Eber N., Fodor-Csorba K., Toth-Katona T., Vajda A., Jadzyn J., Institute of Exprimental Physics SAS, SK

The aim of this study was to investigate how the shape of magnetic particles dispersed in the liquid crystal influences the critical magnetic field of structural changes. The experiment showed parallel initial orientation between liquid [...]

DC and AC dielectric properties transformer oil based magnetic fluid

Timko M., Kopcansky P., Tomco L., Marton K., Koneracka M., Herchl F., Tomasovicova N., Institute of Exprimental Physics SAS, SK

The comparison of the AC-dielectric breakdown strength of transformer oil based magnetic fluid with pure transformer oil confirmed better insulating properties of magnetic fluid in external magnetic field. The better heat transfer properties provided by [...]
