Abstract:
A method comprising:placing a vessel containing a solution including magnetized substances and non-magnetized substances into a magnetic device, the magnetic device comprising first and second north polar magnets, first and second south polar magnets, and first, second, third and fourth interpolar magnets, wherein the first north polar magnet is adjacent to the first interpolar magnet, which is adjacent to the first south polar magnet, which is adjacent to the second interpolar magnet, which is adjacent to the second north polar magnet, which is adjacent to the third interpolar magnet, which is adjacent to the second south polar magnet, which is adjacent to the fourth interpolar magnet; incubating the solution in the magnetic device for a period of time sufficient to allow the magnetized substances to migrate radially toward the interior wall of the vessel; and removing a sample of the solution from the center of the vessel, wherein the removed solution contains non-magnetized substances.
