    Magnetic fluid hyperthermia is based on the conversion of magnetic energy to heat mediated by loss processes, namely - hysteresis power losses, originating in the irreversibility of the magnetization process - Néel relaxation, conditioned by the spontaneous rotation of the magnetic moments of the particles,- friction losses due to the Brownian rotation of the magnetic particles as a whole. From the point of view of achieving the highest possible heating power it is necessary to adjust the parameters of the AC magnetic field to the characteristics of the system of particles or vice versa to tailor their properties to the available or admissible parameters of the AC field facility. Further regardless of the mechanism, the magnetic heating in the vicinity of Tc gradually decreases and it is switched off when the transition temperature is achieved. This behaviour can be used as a mechanism of the temperature self-controlled and prevent local overheating of the healthy tissue.
