Ferrofluid - Wikipedia
网页t. e. Ferrofluid is a liquid that is attracted to the poles of a magnet. It is a colloidal liquid made of nanoscale ferromagnetic or ferrimagnetic particles suspended in a carrier fluid (usually an organic solvent or water). [1] Each magnetic particle is thoroughly coated with a surfactant to inhibit clumping.

Ferrofluid - an overview | ScienceDirect Topics
网页A ferrofluid is defined as a suspension of magnetic particles in a carrier liquid, with high saturation magnetization. Ferrofluids can be considered stable colloids [1], such that the particles have an average diameter of up to 100 nm. In other words, ferrofluid is ferrimagnetic nanoparticles in a carrier fluid.
