As written in the Wikipedia:
"A ferrofluid is a liquid that becomes strongly polarised in the presence of a magnetic field. Ferrofluids are composed of nanoscale ferromagnetic particles suspended in a carrier fluid, usually an organic solvent or water."
This is a nice video I found in YouTube showing experiments dealing with shape manipulation of a ferrofluid by a magnetic field. Very beautiful. If you cannot see the image link below, just click here.
