Magnetic Snake

Caption: Alternating magnetic fields create snake-like chains of magnetic particles suspended in fluid. The snakes direct the flow of the surrounding fluid along their lengths, potentially leading to new methods to control fluids in chip-based chemical analysis. (Video clips of the snakes in action are available to journalists on request.)
