Abstract

The wake potential of a test dust particulate due to an ion cyclotron wave in a dusty plasma with streaming ions is calculated. The role of the external magnetic field on the periodic attractive forces is clarified. The amplitude of wake potential is reduced because the overshielding by streaming ions is inhibited in the presence of the external magnetic field.
