Magnetic Fluid

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.

its apreciated for people who post educated videos on ,metacafe...thats a nice one i could show and discuss to younger ones..

no picture

hottened led atracted by electromagnet. nice.

Are they producing something or is just an experiment lab for educational purposes?

This one had been shown on Discovery channel. The Ferrari use this for their new anti-shocks system on the 500 GTB Fiorano

to watch

:X:X

Can you explain what is that ?

nice 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.....

WTF?

COULD BE ORGANIC MAGNETIC SUBSTANCE JUST LIKE RUBBER MAGNETS.

must 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

i think that's the same liquid as in a humvee suspension.

what liquid is that?

it not interesting.. just S**t
