A ferrofluid (from the Latin ferrum, meaning iron) is a liquid that is highly polarized in the presence of a magnetic field. Ferrofluids are suspended are of nanoscale ferromagnetic particles in a carrier fluid, usually an organic solvent or water. The ferromagnetic nano-particles are coated with a surfactant to prevent agglomeration (due to van der Waals and magnetic forces). Although the name may suggest otherwise, may not need ferrofluids display ferromagnetism, since they do not retain magnetization in the absence of an externally applied field. In fact, ferrofluids display paramagnetism, and are often called “superparamagnetic” due to their large magnetic susceptibility. True ferromagnetic fluids are currently difficult to establish.
