Playing with FerroFluid - Part 1

http://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.

This is the messiest crap in human history. It's almost impossible to handle it without staining your hands and everything within a five-foot radius.

I wish I could find a very durable Pyrex jar with a flat bottom, a tight-sealing lid, and no markings.

is tht micr toner ?

[mrunoqazz]

would like to see what happens When you drop the magnet inside the bottle

@TheNilvarg No, You want to know what the messiest crap in human history is? War. Lives lost, loved ones murdered, all over what? Most of the time it's politics, other times it's for freedom. And some, and these are the rare cases, are over territory. War, my friend, is the messiest crap in human history. Thumbs up if you agree.
