Disclosed herein is an apparatus for separation of diamagnetic particles of sub-micron diameter from a fluid. The disclosed apparatus includes a first magnetic coil including a hollow center and a separation unit including an outer enclosure and a second magnetic coil. The second magnetic coil includes a single-layer of windings of a magnetic wire and at least one nonmagnetic wire on a nonmagnetic core where the first magnetic coil houses the separation unit in the hollow inner center. Also disclosed herein is a method of using the apparatus.
