A ferrofluid is a liquid that has a strongly magnetic attraction, composed of nanoscale particles of magnetite, hematite, or other iron compound. They are used currently in technology for forming seals around spinning hard discs, but are being heavily experimented with for future uses in engineering and medicine.
