In this paper control of microbubbles in still water is attempted. Microbubbles are generated by electrolysis in water tank. These microbubbles are electrified by cationic surfactant or magnetized by magnetic particles. By applying electric or magnetic field these microbubbles are moved. Influence of applied electric or magnetic field on velocity of microbubble is examined. Electrified microbubbles are successfully moved toward electrode. Velocity of these microbubbles seems almost independent of their diameter. When concentration of surfactant is higher than that of critical micellar concentration (CMC), this trend is remarkably observed. On the other hand it is shown that Magnetized microbubbles don’t move toward intended direction.
