Description
The hyperthermia generated by variable magnetic fields is a promising power method for oncological therapy, because apoptosis is induced in tumor cells at temperatures between 42 and 45 degrees Celsius. It is known that an alternating magnetic field on the FeO4 magnetite particles produces heat through three paths: is generated by parasitic currents, lost in hysteresis cycles and losses by magnetization relaxation; taking advantage of the energy losses through the joule effect and the transformation into heat, a simulation is shown in COMSOL about the temporal distribution of temperature in transformed biological systems, to have an estimate of the properties and behavior of the temperature gradient when magnetic hyperthermia is generated in human transformed tissue.
