Primordial cosmological hypermagnetic fields polarize the early Universe plasma prior the electroweak phase transion (EWPT). As a result of the long range parity violating gauge interaction present in the Standard Model their magnitude gets amplified, opening a new perturbative way of seeding the primordial Maxwellian magnetic field at EWPT.
