Micrograph of the surface of ferrofluid,taken with episcopic lighting and Normarski Interference Contrast (DIC). Ferrofluids are colloidal liquids consisting of nanoscale ferromagnetic,or ferrimagnetic,particles suspended in a fluid,usually an oil. Each tiny particle is thoroughly coated with a surfactant to inhibit clumping. One application of ferrofluids is to keep dust off of the drive shafts of magnetic disk drives,which it does by creating a liquid seal held in place by magnetic fields. Object size; 0.5 mm | |
