The effective moment method is used to calculate the dielectrophoretic forces exerted on a homogeneous spherical particle by external non-uniform electric fields. We examine the problem of a spherical particle placed in the center of two types of microsystems, to asses the accuracy of the dipole moment method for situations of slightly and strongly non-uniform electric fields. The results are compared against net force calculations using the Maxwell stress tensor method.
