Recent observational consequences have shown the existence of $${\fancyscript{O}}(10^{-6}) ~\mathrm{{G}}$$ magnetic fields in galaxies and clusters of galaxies at redshift[1-3]. One of the scenarios to realize this is an amplification of the magnetic fields by the galactic dynamo mechanism (e.g. [4]), which requires $${\fancyscript{O}}(10^{-20}) ~ \mathrm{{G}}$$ seed fields prior to the galaxy formation.
