Ferrofluid: How it works (by Michael Flynn)
www.FunExhibits.com Ferrofluid is an assemblage of magnetic particles engineered at the nanoscale, 100 times smaller than the wavelength visible light. Although too small to be imaged with microscopes, nano-products harness surprising properties from nanoscale physics for use in the macroscale world. www.FunExhibits.com
Ferrofluid Sculpture
Ferrofluid Sculpture A steel sculpture with changing magnetisation is coated with ferrofluid. The fluid is pulled in the direction of increasing flux density and forms peaks, which become smaller in higher flux density. At an accumulation of fluid at ridges, the flux density at the surface decreases. The flow and the distribution of the fluid can be observed at several characteristic locations. The centre part of the sculpture is a conical spiral that has one, three or even more tracks of peaks depending on the magnetisation. Further tracks are built at the crown and at the ridge of the central hexagon. The crown has horizontal cavities that discontinue the gradient of flux density. On the way to the top the fluid is accumulated until the cavities are bridged by fountains. On the way back the fluid falls in large drops over the gap. The horizontal cavity at the ridge of the hexagon remains filled at the retreat. With increasing magnetisation the fluid at the ridge rises steeply as the flux density on the hexagon is slightly higher than at the other side of the cavity. One can also just enjoy looking at the movements of the object. ------------------------ Ferrofluid Figur Eine Stahlplastik wird bei zunehmender Magnetisierung von magnetischer Flüssigkeit überzogen.

Dynamic sculpture with ferrofluid
Sachiko Kodama's "Morpho Tower": "This work is conceptualized as an "organic tower." The magnetic fluid, with a smooth black surface that seems to draw you in, reaches the top of the tower, spreading like a fractal, defying gravity. The form and texture of the physical surface of the tower constantly alter between the hard iron core and the changing form of soft fluid. This is a dynamic sculpture, with reactable fluid surface".

How to make Ferrofluid
Here's a relatively simple method to make ferrofluid, a very interesting liquid that responds to magnetic fields. You'll need the following chemicals: 20mL 1.5M FeCl3 solution 10mL 1.5M FeCl2 solution 150mL Household Ammonia 5mL Oleic Acid 100mL Kerosene My iron chlorides probably weren't precisely as listed above, because I made them by dissolving iron in HCl (see my other video here: www.youtube.com ). What you want to shoot for is a 2:1 ratio of FeCl3:FeCl2. Ferrofluids consist of 3 parts: a magnetically responsive material, a surfactant, and a carrier fluid. The surfactant serves to suspend the magnetic material and keep it from clumping together. Here, our material is magnetite, the surfactant is oleic acid, and the carrier fluid is kerosene. First, we will make the magnetically active material. Mix the two iron chlorides together, and pour the mixture into 150mL of household ammonia solution. This initiates a complex reaction that produces tiny particles of magnetite, Fe3O4, in ammonium chloride solution. Next, we will coat the material in the surfactant. Take the solution outside or in a fume hood, and heat it to near boiling. Then add 5mL of oleic acid with lots of stirring, and continue to heat until the smell of ammonia disappears. This usually takes about an hour - swirl the solution often to keep the magnetite suspended and to let the oleic acid attach to it completely. The acid initially reacts with the ammonia to form ammonium oleate, a slightly soluble soap ...

Me playing with some ferrofluid and rare earth magnets. This stuff is so damn reflective!
Ferrofluid Demo 1
This is a test video showing some of the ferromagnetic sculptures that will be displayed at the Johns Hopkins 2011 Physics Fair.
Ferrofluid on the track of a Meatgrinder
Ferrofluid is attracted by magnetic flux. It flows with the gradient. A track with continuously increasing flux density is formed by a conical screw. Such a high pitch, conical steel-screw is difficult to make. It is much easier to just take it form discarded equipment, like in this case from a meatgrinder. A meatgrinder core is tested in the field of an adjustable DC Magnet. The flux lines emerging from track at the ridge of the thread shall be of increasing density from bottom to top. To visualise the flux density on the track, identical steel spheres are attached at high flux. With decreasing flux they will fall down when at their location the flux density falls under the critical value. With continuously decreasing flux they shall fall down in sequence from bottom to top. The handmade screw shows a suitable increasing line with some distortions. The final test shows that the meatgrinder screw is capable to levitate the ferrofluid on the track at the ridge of the thread from the basin to its top. ---------------------------- Mit Ferrofluid auf der Spur des Fleischwolfs Ferrofluid wird vom Magnetfeld angezogen.

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.

Playing with FerroFluid - Part 1
kjmagnetics.com - The ferrofluid in this video is in a plastic jar with no other liquids. This is the reason the fluid "stains" the sides of the jar. The magnet is a rare-earth, neodymium ring. In Part 2 we will add another liquid to the container for a totally different effect. From Wikipedia Ferrofluids are colloidal mixtures composed of nanoscale ferromagnetic, or ferrimagnetic, 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 forces and magnetic forces). Although the name may suggest otherwise, ferrofluids do not display ferromagnetism, since they do not retain magnetization in the absence of an externally applied field.

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.
Spacelab - Ferrofluid Thermal conductivity in Microgravity
According to my research, this experiment has not been done before on ISS. FerroFluids - Ferrofluids are colloidal liquids made of nanoscale ferromagnetic, or ferrimagnetic, particles suspended in a carrier fluid (usually an organic solvent or water). It becomes strongly magnetized in the presence of a magnetic field. In microgravity... natural convection, bouancy forces, sedimentation are absent. To be precise, even basic principles such as 'fluid flow' are greatly altered in Microgravity. So, due to applied magnetic field "Thermomagnetic convection" is also altered to a small extent in microgravity. Hence, Thermal conductivity (Rate of heat flow) in a FerroFluid... will be different in microgravity. Applications- Study of this experiment has applications in developing advanced cooling systems, heat transfer systems, Ferrofluid deformable mirrors and other lot of applications in Aerospace industry. NOTE :- The magnetic field used for the experiment is of small magnitude... hence it doesn't interfere with operation of other instruments onboard the ISS. By plotting the graph of Temperature versus Time for the obtained experimental data thermal conductivity of ferrofluids can be calculated. The data can be fed to the computer onboard the ISS which can calculate the thermal conductivity. Thank you for sparing your precious time and watching the video.

Magnetic liquid - ferrofluid - магнитная жидкость / Dancing Ferrofluid
A magnetic liquid or ferrofluid is a colloidal mixture of magnetic particles (~10 nm in diameter) in a liquid carrier. Ferrofluids can be suspended in water or in an organic fluid. When no external magnetic field is present the fluid is not magnetic and the orientation of the magnetite particles is random. However, when an external magnetic field is applied, the magnetic moments of the particles align with the magnetic field lines. When the magnetic field is removed, the particles return to random alignment. These properties can be used to make a liquid that changes its density depending on the strength of the magnetic field and that can form fantastic shapes. Магнитные жидкости, представленные на видео, выпускаются на базе Ивановского государственного энергетического университета. Более подробную информацию можно получить на сайте www.ispu.ru/node/5796.

Nano Drop, FerroFluid Desk Toy available at www.magnetic-gadgets.com
Ferrofluid is dark oily magnetic material with amazing properties. When an external magnetic field is applied to the Ferrofluid inside the Nano Drop bottle, the magnetic particles in the Ferrofluid orient themselves almost instantly to the magnetic field lines of the included Neodymium magnet. This creates amazing spiky fractals and geometric forms that allow you to see the magnetic field of the magnet in 3 dimensions. When the magnet is removed, the particles go back to their normal alignment very quickly. This Ferrofluid Nano Drop desk Toy is sure to amaze everyone at the office!

Playing with FerroFluid - Part 2
kjmagnetics.com - The ferrofluid in this video is in a glass bottle with regular old, store bought rubbing alcohol. This prevents the ferrofluid from sticking to the sides of the glass. The first magnet in the video is a small neodymium cylinder (part # D78). The second magnet used is a medium-sized, neodymium ring (part # RX8CC). From Wikipedia Ferrofluids are colloidal mixtures composed of nanoscale ferromagnetic, or ferrimagnetic, 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 forces and magnetic forces).
