The mesmerizing pull of ferrofluids
WebProcedure modified by Jonathan Breitzer and George Lisensky from “Preparation and Properties of an Aqueous Ferrofluid” by Patricia Berger, Nicholas B. Adelman, Katie J. … WebMagnetic fluids (ferrofluids) are oil– or water– based colloidal suspensions of ferromagnetic nanoparticles, such as Co–ferrite (CoFe2O4) and magnetite ( Fe3O4) [l]. Because they are fluids, these suspensions can flow in response to applied forces such as a magnetic field [2, 3].
