Abstract
The recent discovery and independent confirmation of biogenic magnetite in human tissue has led to speculation not only on its role in the central nervous system but also on mechanisms for explaining the possible interactions of weak magnetic fields with human physiology. Experimental evaluation of human tissue samples indicates that biogenic magnetite is present in human brain tissue as well as the heart, liver and spleen. This has led to theoretical models showing how these particles may interact with magnetic fields at both extremely low frequency (ELF) bands and microwave frequency bands1,2,3. In addition to the implications for interactions due to the magnetic properties of these magnetite particles, they also have very different electrical conductivity when compared to human tissue.
