Abstract
Microfluidic channels utilizing magnetohydrodynamics are used to pump very small volumes of solution. The channels have electrodes along the walls and a current carrying species within a solution carries current through the solution. The combination of the electric and magnetic fields causes the solution to flow through the channel.
