MAGNETIC FLUIDS

Magnetic fluids are colloidal dispersions of ultrafine subdomain ferro- or ferrimagnetic particles in various carrier liquids. Macroscopically the ferrocolloids are similar to ordinary liquids but they obey unusually strong superparamagnetic properties. That means, that the use of external magnetic fields provides strong magnetic forces acting on the fluid. Thus, a control of the flow characteristics and the properties of magnetic fluids by magnetic fields become possible. The "smart" or even "intelligent" properties of ferrocolloids have been used to develop various technical applications, some of them gaining high commercial importance and application in every-days live (sealing of hard disc drives of personal computers, loudspeaker cooling, magnetofluid bearings and lubricants, various sensors etc.).
