Liquid Magnet Sculpture A ferrofluid (from the Latin ferrum, meaning iron) is a liquid which becomes strongly polarised in the presence of a magnetic field. Ferrofluids are composed of nanoscale ferromagnetic particles suspended in a carrier fluid, usually an organic solvent or water. The ferromagnetic nano-particles are coated with a surfactant to prevent their agglomeration (due to van der Waals and magnetic forces). Although the name may suggest otherwise, ferrofluids do not display ferromagnetism, since they do not retain magnetisation in the absence of an externally applied field. In fact, ferrofluids display paramagnetism, and are often referred as being "superparamagnetic" due to their large magnetic susceptibility. True ferromagnetic fluids are difficult to create at present. Tags: Amazing Liquid Sculpture

Sachiko Kodama: When I Met This Material While most visual artists prefer traditional materials such as oil, acrylic, bronze and ceramic, Tokyo-based SACHIKO KODAMA prefers FERROFLUIDS. Composed of magnetic nanoparticles, ferrofluids often contain high levels of iron and, as such, are deeply affected by and responsive to the presence of magnetic fields. While the NASA-developed ferrofluids are being used increasingly for commercial applications - on everything from compact disks to weight-responsive car suspension systems - Kodama is revolutionary in applying their widely dynamic qualities to the fine arts arena. Using a computer to manipulate electro-magnetic fields in the sculptures, Kodama coerces her stunning ferrfluid pieces to grow and disintegrate, flower and shed, and constantly reinvent themselves without the aid of animatronics or video wizardry.

Ferrofluids: Introductory History and Applications Get introduced to the developmental story of the mysteriously fun magnetic fluid, ferrofluid. Composed of magnetite, a surfactant, and a carrier fluid, ferrofluid exhibits interesting and useful magnetic properties that improve heat flow in high-end speakers. Future applications in space, biology, and the military, amongst other fields, leave many new directions for this fairly old material. This video was produced for a Stuff of History project at Olin College with professors Rob Martello and Jon Stolk. Made by Andy P, Sarah A, and Mike T.

Ferrofluid of Seventeen Evergreen Ferrofluid raw footage from the music video for Seventeen Evergreen, "Haven't Been Yourself (Lucky Number Music)", Directed by Encyclopedia Pictura. A ferrofluid is a liquid that becomes strongly polarised in the presence of a magnetic field. Ferrofluids are composed of nanoscale ferromagnetic particles suspended in a carrier fluid, usually an organic solvent or water. The ferromagnetic nano-particles are coated with a surfactant to prevent their agglomeration (due to van der Waals and magnetic forces). Although the name suggests otherwise, ferrofluids do not display ferromagnetism, since they do not retain magnetisation in the absence of an externally-applied field. In fact, ferrofluids display paramagnetism, and are often referred as being "superparamagnetic" due to their large magnetic susceptibility. Truly ferromagnetic fluids are difficult to create at present, requiring high temperatures and electromagnetic levitation.
