Description
Surfactants are responsible for prolonging the settling rate in ferrofluids but they also reduce the fluid’s magnetic properties (specifically, the fluid’s magnetic saturation).True ferrofluids are stable. This means that the solid particles do not agglomerate or phase separate even in extremely strong magnetic fields..Ferrofluids have an exceptionally high magnetic susceptibility and the critical magnetic field for the onset of the corrugations can be realised by a small bar magnet.
