A ferrofluid or ferromagnetic liquid is a fluid that turns out to be strongly magnetised within sight of an attractive field. Ferrofluids are colloidal fluids made of nanoscale ferromagnetic, or ferrimagnetic, particles suspended in a bearer liquid (usually a natural dissolvable or water). Each minuscule molecule is wholly covered with a surfactant to restrain amassing. Large ferromagnetic particles can be torn out of the homogeneous colloidal blend, shaping a different cluster of attractive residue when presented to solid attractive fields.
