Abstract The Magnus effect introduced near the turbulent boundary layer in the flow of rotating disk galaxies in the intergalactic medium (IGM) is discussed. TheMagnus effect is expected to develop an extra pressure on the outer edges of the gas disk in galaxies. It is found that for the Milky Way, the pressure due to Magnus effect is significant compared to the thermalpressure and the gravitational restoring pressure in the gas disk. It is speculated that the Magnus effect is playing some role in maintaining various morphologicalasymmetries in disk galaxies. Due to higher IGM densities at high redshifts, the role of the Magnus effect on galaxies is expected to be crucial at earlier epochs.
