Magnetic cluster and its applications

We succeeded in extracting magnetic clusters from an intelligent fluid that is responsive to a magnetic field. We can freely control the scale of the magnetic cluster in the range between millimeter and micrometer, with the form remaining stable without the presence of a magnetic field. We discovered an algebraic rule governing the relation between the scale of the magnetic cluster and the strength of the applied magnetic field. We could use the behavior of the magnetic cluster in certain engineering applications. In the present paper, we introduce the effect of the magnetic cluster on damper, polishing and composite material.
