Abstract

The influence of the hypothetical extragalactic magnetic field upon the peripherical morphological features of spiral galaxies is examined- When the angle between and the rotation axis is neither 0° nor 90°, warps are expected to be produced. In such a case the spatial distribution of warps should not be random. This fact seems to be confirmed by observations. From the distribution it is possible to obtain the direction of B in the 20Mpc-neighborhood of the Milky Way.
