Description
Primordial magnetic fields (PMFs) offer a simple explanation for the origin of galactic magnetic fields as well as of the purportedly detected magnetic fields in cosmic voids. In this talk, I show how PMFs can enhance the abundance of dark matter minihalos of masses between 10^3-10^-11 solar masses. I conclude by arguing that search for dark matter minihalos can potentially provide the most sensitive probe for PMFs.
