Claim:
1. A magnetic device comprising: a substrate; an array including a plurality of magnetic particles arranged in a single layer on the substrate, wherein a magnetic dipole moment direction of each magnetic particle in a majority of the magnetic particles alternates with respect to a magnetic dipole direction of a directly adjacent magnetic particle in the array, wherein an average maximum dimension of each particle of the plurality of magnetic particles is between about 50 nm to about 100 microns, and wherein directly adjacent particles within the array are separated by a spacing of 5 nm or less; a fluid flow channel having a bottom surface arranged adjacent to the array, wherein the magnetic dipole moment direction of each magnetic particle in the majority of the magnetic particles is oriented orthogonal to the bottom surface of the fluid flow channel; and a chaotic mixer arranged in the fluid flow channel, wherein a structure of the chaotic mixer is arranged and configured to create a fluid force, within a fluid flowing in the fluid channel, in a direction toward the array.
