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.

  • Can this be used to make sex toys?

  • It is NOT solid guys. N-O-T. It just forms into a shape in the presence of a magnetic force. If you touch it, it will still act like water.

  • Fucking magnets, how do they work?

  • I find this difficult to masturbate to.

  • @metalstorm997 Not at all; I am genuinely interested. Being British, we would spell it "haemochromatosis" but that seems to be an inherited disease where normal amounts of mineral iron in a normal diet result in sickness, rather than over-ingestion, though I suppose it result in the same thing.

    Nice one.

  • @BeautifuICyberBuIIy it's Hemochromatosis

    sorry if i sound like a jerk

  • @hybridwolf55 Death by hyperferraemia, I would imagine.

  • What happens if one were to drink it?

  • @vancouverprodctions man, im still a human, but my internet speed isnt as slow as urs ))))
