OBJECTIVES Synthesis of ferrofluids, otherwise known as 'liquid magnets'. Exploring some of their interesting properties and analysing their absorption spectra.
BACKGROUND Ferrofluid, first developed and classified in the 1960s by Stephen Pappell at NASA [1], is a colloidal mixture comprising of extremely small magnetic particles (of magnetite, hematite or some other compound, usually containing iron, with dia ≤ 10 nm) suspended in a carrier fluid (usually an organic solvent or water). The…
