Abstract
The physical principles of magnetic hyperthermia are based on the heat generation of magnetic nanoparticles under the influence of applied magnetic fields of different configurations. The choice of a suitable methodology for generating a magnetic field can significantly affect the resulting thermal effect and thus the efficiency itself. The technical details of the apparatus generating a rotating magnetic field and a comparison of the efficiency when the alternating magnetic field is applied are analyzed. While the mechanism of the temperature rise is the same, as shown by the fitting of the dT/dt curves, the intrinsic loss power differs significantly. It was found that the rotating magnetic field produces a thermal effect that is more than twice that of the alternating magnetic field under similar experimental conditions.
