Abstract
The far-field potential of a slowly moving test charge in dusty plasmas is calculated accounting for the dust grain charge fluctuations. It is found that the latter cause a damping, which in turn gives rise to a dipole-like far-field potential. The presence of the dipole-like potential is attributed to the dust grain charge perturbations caused by the oscillating electron and ion currents induced by the motion of a test charge.Keywords
