Magnetic Fluid. Very cool.
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.
you and the other kids need to stop posting things from WIKIPEDIA to here...geshhhh

By royteo 1234492544 Reply Spam [+0] Moderate Up Moderate Down RemoveThis one had been shown on Discovery channel. The Ferrari use this for their new anti-shocks system on the 500 GTB Fiorano

By metafan-india 1233417388 Reply Spam [+0] Moderate Up Moderate Down Removenice one lol
i think that technology has yet to discover some other important facts about magnetic fileds,magnets are going to be the most important elements in the near future.....
magnets are not elements....they are usually made of alloys....nice attempt though.
By jimbo0317 1233735002 Reply Spam [+0] Moderate Up Moderate Down Removestop saying lol wtf roflmao stf stfu on metacafe and youtube
By sooryamericaurstupid 1233305282 Reply Spam [-1] Moderate Up Moderate Down Removeif you don't like it then don't come to these sites.
i also see that you are a racist.
COULD BE ORGANIC MAGNETIC SUBSTANCE JUST LIKE RUBBER MAGNETS.
By supremegod 1233161630 Reply Spam [+0] Moderate Up Moderate Down Removemust be a liquid filled with tiny pieces of iron , remember me when u stick a magnet instead of the oillevel , u get iron particels with oil on your magnet , kinda has the same technique , but that one i think is a elektro-magnet , nice though
By teodor X 1233158736 Reply Spam [+0] Moderate Up Moderate Down Removei think that's the same liquid as in a humvee suspension.
By rusu989 1233126368 Reply Spam [+0] Moderate Up Moderate Down Removewhat liquid is that?
By stogfatha 1233120566 Reply Spam [+0] Moderate Up Moderate Down Removeand why does it keep asking about john connor?
