Magnetite has also dropped from space as ingredients of meteorites. And, Living organisms can produce it as well. In humans, this substance is found in parts of the brain. However, magnetite can have toxic effects due to its charge or magnetic nature and its involvement in oxidative stress or the production of free radicals.
