This work presents numerical study on the feasibility of implementing a newly introduced electromagnetic pump for mixing fluids in microscales. It also introduces an interesting energization scheme that can be used to adjust the mixing length until obtaining complete mixing. The electromagnetic gentle pump was proposed for biomedical applications. It consists of an annular fluidic channel, set of solenoids, two permanent magnets and a cover. The pumping concept depends on controlling the rotation of the two hard magnets placed in an annular channel in opposing polarity under the influence of an electronically controlled moving electromagnetic field. This concept is currently under development for microfluidic applications using polymer micromachining. Results have been visualized through plotting mass fraction contours along the channel length. Results are motivating and showed higher mass fraction of H2O at low channel widths.
