What is ferrofluid?
Ferrofluids are [|colloidal] mixtures composed of [|nanoscale] [|ferromagnetic], or [|ferrimagnetic], particles suspended in a [|carrier] [|fluid], usually an [|organic solvent] or water. The ferromagnetic [|nanoparticles] are coated with a [|surfactant] to prevent their [|agglomeration] (due to [|van der Waals forces] and magnetic forces).

Please wear safety glasses and skin protection, work in a well-ventilated area, and be familiar with the safety data for your chemicals. Ferrofluid can stain skin and clothing. Keep it out of reach of children and pets. Contact your local poison control center if you suspect ingestion (risk of iron poisoning; carrier is kerosene).
