Abstract: We have demonstrated the ability to increase fluid flow rates in microchannels using magnetic nanoparticles that are suspended in the fluid. A magnetic circuit was fabricated to generate a magnetic field gradient and results showed that for |▽B| ∼ 3 T/m, the fluid velocity near the channel edge increased 30 μm/sec. At |▽B| ∼ 5 T/m, the fluid velocity increased 10 - 80 μm/sec from near the edge to the center of the channel. ©2009 IEEE.
