Warning- bad carbon will kill

[o.c.d.]

So I found this at Physicsworld.com."It is also difficult to separate these small moments from the underlying "diamagnetism" of carbon. This is a very weak form of magnetism exhibited by almost all forms of carbon (and, indeed, by many other elements) in the presence of an external magnetic field. The external field alters the orbital motion of electrons and induces a small magnetic moment in a direction opposite to that of the field itself." AND the reason for what is most likely iron in carbon."The main cause for suspicion was that many of the reports claimed to have detected only small magnetic moments, which can simply be due to traces of natural magnetic contaminants. Iron, for example, is the fifth most common element in the Earth's crust, and its black oxide magnetite is everywhere in the air.
