We discuss the possibility of the Mach cone formation involving the modified dust‐acoustic waves in a dusty magnetoplasma composed of electrons and positively charged dust grains. It is shown that the modified dust‐acoustic waves, whose wavelength is of the order of (or shorter than) the electron gyroradius, are one of the viable candidates for the formation of Mach cones in Saturn's dusty rings.
