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.

磁热疗的物理原理基于磁性纳米粒子在不同配置的外加磁场的影响下产生的热量。选择合适的磁场产生方法会显着影响所产生的热效应，从而影响效率本身。分析了产生旋转磁场的装置的技术细节和施加交变磁场时的效率比较。而温升的机理是一样的，如d T /d t的拟合所示曲线，内在损耗功率显着不同。发现在类似的实验条件下，旋转磁场产生的热效应是交变磁场的两倍多。
