The above-mentioned magnetic colloids are not easy to separate using classical magnets. This is due to a small particle size, at which Brownian motion forces are higher than the exerted magnetic force. To enhance phase separation, various magnetic latexes that may interact with nucleic acids were prepared.

A further difference between magnetic and electric forces is that magnetic fields do not net work, since the particle motion is circular and therefore ends up in the same place. We express this mathematically as: W = ∮B ⋅ dr = 0 (21.4.5) (21.4.5) W = ∮ B ⋅ d r = 0.
