Nano magnetite particles are found in the brain. They are associated with schizophrenia, parkinson's disease, aging and etc. Imagine that we are able to make a huge NMR machine and place a live human being in the bore to cause levitation. The diamagnetic particles will orient against the magnetic field and cause levitation. What will happen to the magnetite particles? How many tesla of magnetism will be required to pull it out of the brain? Is it possible to manipulate the diamagnetic particles with RF frequency to enhance the pull of magnetite particles? Physicists please explain and help the world.
