Ferromagnetic Liquid



Uploaded by: FreeScienceLectures
Video Description:
http://www.FreeScienceLectures.com A ferrofluid 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. Truly ferromagnetic fluids are difficult to create at present. --- It's Never too Late to Study: http://www.FreeScienceLectures.com --- Notice: This video is copyright by its respectful owners.

For some really cool art made with ferrofluid and an interview with the artist - search for the video 'When I Met This Material'

its oil with Iron particles in it might be a bit...uncomfortable
never too late :D:D ... ( 9 months ago by brumanima)
never too late :D:D lol i like it :D

they do...i just ordered a bottle yesterday ^_^ i cant wait!
that cannot be real ... ( 8 months ago by whitecallum)
that cannot be real cuz mathmaticly and scientificly you can not get magnetic liquid
That can't be true ... ( 8 months ago by dstudmuffinv)
That can't be true because they just mathematically and scientifically got magnetic liquid.

what the hell are you talking about? did you continue beyond hischool?
drop it all over ... ( 8 months ago by metube5303)
drop it all over the floor and poick it up with the magnet
whoa wtf what is ... ( 8 months ago by seanpg95)
whoa wtf what is that do u make that or buy it or wtf
even though i know ... ( 8 months ago by PetercAW)
even though i know nothing about this, i assume from the description that it's magnetic particles in water, idiot.

ever thought of glancing of the name of this compound fellas?
(ferro)magnetic look at the periodic table at iron, it isn't [I] it is [FE] because iron is the moden name the latin scientific name of iorn is ferrum hmmmm i think there is iron in there

lol y lead is magnectic and guess what makes some printer inks black you guessed it and what is that omg ink is liquid!

This principle would make an awesome future gasket that could be used in nano applications. Imagine having th liquid contained in an area and being able to turn a electromagnet on to activate the liquid to become solid instantly. What if you could have a pc hooked up to the electromagnets to change an appearance of an object or even hide or hide an object kinda like a chameleon shell.
its called ... ( 5 months ago by survival12345)
its called MagnaView fluid... it cost 15$ (u.s.) for 30 ml, but gets cheaper the more you buy... its not 'hard' when its magnetized, (when it 'spikes' up), its still just an 'oily liquid'... i was gonna make a kick ass mace or sword out of the stuff but that didnt work.. if you drop almost any shape magnet into the stuff it becomes a liquid ball and will race around the container, making me think this will be a great engine or ball-berring etc. lubercant..

Fuck yea!!! a ... ( 3 weeks ago by BabyWhaleNutz)
Fuck yea!!! a crude outburst to such an enlightening conversation! the fluid is definitely cool, and has tons of real world applications.
