Abstract—The magnetic flux control of focusing deep hyperthermia inductive heating are presented for breast cancer treatment by using ferro-fluid nanoparticles in conjunction with magnetic shielding system. It is a technique to control magnetic field intensity and relocate the heating area in hyperthermia therapy to destroy cancerous cells, without damaging the surrounding healthy tissue by using a cylindrical magnetic shielding system in conjunction with ferro-fluid. The simulation and investigations were carried out using a lossy medium. The inductive applicator is a ferrite core with diameter of 7cm, excited by 4MHz signal. The results showed that the position of heating region can be controlled and relocated by changing the orientation of the ferrite core with shielded system. These results demonstrate that it is possible to achieve higher temperatures and to focus magnetic field intensity where the nanoparticles and magnetic shielding system are used. The advantage of the magnetic shielding system is that it can be applied to prevent the side-effects of hyperthermia cancer treatment by inductive heating.
