Abstract
We study the effects of the cosmic ray instabilities excited by the current associated with an inhomogeneous distribution of sources of extragalactic cosmic rays, with average density ns. We find that under certain conditions, the resulting current can excite a non-resonant instability that forces particles with energy below some critical value to be confined within a distance n−1/3 s from the sources. This also causes the existence of a pervasive intergalactic magnetic field with a strength of order ∼ 0.01 nG.
