Origin of magnetic fields may lie in special relativity's spacetime distortions

( -- Magnetic fields play an important role on scales ranging from the sub-atomic to the cosmic, from particle spins to galaxy clusters. Although scientists know how to create and manipulate magnetic fields, as well as use them for a variety of applications from computers to credit cards, they still don't have a universal theory of how magnetic fields initially originated in astrophysical settings.
