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, etc. 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.
