“…Jafelice and Opher [9] suggested that the large-scale magnetization of the intergalactic medium is due to electric current carrying extragalactic jets, generated by active galactic nuclei at high z. The action of the Lorentz force on the return current expanded it into the intergalactic medium.…”

“…Many other scenarios have previously been suggested. We alone have suggested three other possible scenarios: (A) Non-minimal electromagnetic-gravitational coupling (i.e., rotation of a neutral body produces a magnetic field) (44,45,46); (B) Collimating magnetic fields of extragalactic jets spread out into the intergalactic medium (a magnetic field in the intergalactic medium will remain there undiminished for the age of the universe) (47); and (C) Density gradients not parallel to temperature gradients in primordial supernovae explosions (48).…”

“…A potential problem with these approaches is that the magnetized winds may not actually be able to penetrate much (Jafelice & Opher 1992). A completely different idea is to produce strong enough seed magnetic fields in protogalactic turbulence by the small-scale dynamo, whose time scale is much shorter (10 7 yr); see Beck et al (1994) for more details.…”
