Abstract

V magistrskem delu je opisan postopek merjenja magnetnih izgub pri vzorcu magnetne tekočine kateri se segreva pod vplivom izmeničnega magnetnega polja. Segrevanje tekočine oziroma hipertermija je raziskana eksperimentalno za izbrane frekvence magnetnega polja. Meritve so bile izvedene po kalorimetrični merilni metodi, ki temelji na merjenju zvišanja temperature vzorca. Rezultati karakterizacije so podani v grafični in tabelarični obliki za konstantne frekvencah ter konstantne amplitude magnetne poljske jakosti. Na osnovi dobljenih rezultatov so določene krivulje specifične izgube magnetne tekočine SAR. Rezultata prikazujeta eksponentno odvisnost za primer spreminjanja amplitude ter prav tako eksponentno odvisnost izgub pri spremembi frekvence.

Secondary title:	THE DEPENDENCE OF MAGNETIC HYPERTHERMIA MAGNETIC FLUIDS ON THE FREQUENCY FIELDS
Secondary abstract:	The master thesis describes the process of measuring the magnetic losses in the pattern of magnetic fluid which is heated under the influence of an alternating magnetic field. The liquid heating or hyperthermia has been studied experimentally for the selected frequency of the magnetic field. Measurements were carried out by calorimetric measurement method based on measuring the increase in temperature of the sample. The results of the characterization are presented in graphical and tabular format for constant frequency and constant amplitude magnetic field strength. Based on the results obtained are set curve-specific loss of magnetic fluid SAR. The results demonstrate an exponential dependence for example, changing the amplitude and also the exponential dependence of loss when changing frequencies.
