A ferrofluid is a liquid made of nanoscale ferromagnetic particles dispersed evenly throughout a carrier fluid. Ferrofluids become very strongly magnetized in the presence of a magnetic field. Here, Fe3O4 magnetite nanoparticles are produced by mixing Fe(II) and Fe(III) salts together in a basic solution. Safety: Wear eye protection

How to Synthesize Ferrofluid (Liquid Magnets)

Jun 04, 2020 Ferrofluids can be suspended in water or in an organic fluid. A typical ferrofluid is about 5% magnetic solids, 10% surfactant, and 85% carrier, by volume. One type of ferrofluid you can make uses magnetite for the magnetic particles, oleic acid as the surfactant, and kerosene as the carrier fluid to suspend the particles.
