|Ferrofluids are magnetically controllable colloids, produced
in laboratory, which have an enormous variety of uses,
technological, biological and medical.
A discussion about the different kinds of ferrofluids and
their general properties will be presented. The applications
may also be divided into classes, which include dynamical
seal, heat transport, lubrication, drugs carrier in medicine,
Finally, we shall present briefly the computer simulation
of the dynamics of their magnetic particles. Some
approximations which have been used by other authors will
be discussed and the results wil be compared.
