Abstract
The method includes placing a vessel containing a solution having magnetized substances into a magnetic device. The solution is then incubated in the device for a period of time sufficient to allow the magnetized substances to migrate radially toward the interior wall of the vessel, and a sample of the solution removed from the center of the vessel would contain non-magnetized particles. The magnetic device is made of four polar magnets and a plurality of interpolar magnets disposed therebetween. The interpolar magnets are positioned to progressively rotate towards the orientation of the four polar magnets creating an even flux within the solution thereby causing the radial movement of the magnetized substances toward the inner wall of the surrounding magnets.
