In this chapter, the use of nanomagnets can resolve the issue of the selection of the zone to heat. In fact, in this case the dissipated heat is directly proportional to the concentration of magnetic nanocrystals. The heated zone will then be the reflection of the bioselectivity of the nanomagnets for the pathology to be treated. The frequency of the variation of the magnetic field used (between 100 and 300 kHz) will be a thousand times lower than the one used in a classical thermotherapy irradiation. This allows a heat dissipation caused exclusively by the interaction between magnetic field and magnetic nanocrystals.
