Abstract
A new kind of magnetoacoustic wave which is different from the usual compressional hydromagnetic wave (fast Alfvén wave) is shown to exist in a magnetized, three component dusty plasma. The "dust-magnetoacoustic mode" arises due essentially to the effects which account for the departures from the frozen-in-field approximation for the ion dynamics. Other normal modes in a magnetized dusty plasma are also pointed out.Keywords
