摘要： Provided is an orientation control device for a magnetic fluid, includes: a magnetic fluid having magnetic nanoparticles; an induction power generation unit configured to include a silicone tube through which the magnetic fluid passes and a solenoid coil which is wound around a predetermined section outside the silicone tube to generate induced power when the magnetic fluid passes through an inner side of the silicone tube; and a magnetic pole direction control unit configured to include a silicone tube at an entrance portion of the induction power generation unit and a solenoid coil wound around a predetermined section outside the silicone tube and generating a flux when a current flows therein so as to control pole orientation of the magnetic fluid.
