Ferrofluid - Wikipedia
网页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.

A Guide to the Theory, Properties and Applications of Magnetic Fluid
网页2012年9月5日 · Fluid creates magnetic sculptures. Theory behind Ferrofluid. The term ‘ferrofluid’ is a portmanteau of ferromagnetic and fluid and is used to describe a fluid that is strongly magnetized by a magnetic field. This occurs because the fluid is composed of tiny magnetic particles, up to 100 times smaller than the wavelength of visible light.
