An alternative explanation of galactic warps is proposed, in which the intergalactic magnetic field (IGMF) is responsible for these structures. The model predicts that, to be efficient, the magnetic field must have a direction not much different from 45 deg with the galactic plane. The required values of the field strength are uncertain, of about 10 nG, higher values being favored. When observed galaxies are used to determine the directions of the IGMF responsible for their warps, a noticeable regular alignment is found. The IGMF within 20 Mpc of the Galaxy points in the direction b(II) = 28 deg, l(II) = 123 deg.
