We study limits on a primordial magnetic field arising from cosmological data, including that from big bang nucleosynthesis, cosmic microwave background polarization plane Faraday rotation limits, and large-scale structure formation. We show that the physically-relevant quantity is the value of the effective magnetic field, and limits on it are independent of how the magnetic field was generated.

Magnetic fields linearly change the exponential decay rate of light-nucleus wave functions, which the authors argue could enhance low-energy fusion reactions and, at implausibly high field strengths, affect the Big Ba...
