Conclusions<br />
In this article computation of dielectrofoertic force acting on dielectric particle immersed in<br />
dielectric fluid and utilizing finite element method is presented. It was shown how to compute<br />
dependence of the FDEP from fluid and particle permittivitis and particle dimensions.<br />
