MAGNETIC HEALTH EFFECTS

[Greg Petersen]

   Could someone explain in few words what these magnetic bacteria realy
are? This is the firs time for me to hear that there is an organism that
is able to utilize magnetic fields for movement (or is it just for
orientation?).
   Also, how could these bacteria utilize iron as an energy souce?
   I would appriciate if someone explained these things briefly.
