SCIENCE - Magnetic forces without magnets: Physicist calculates field strengths in the early universe

Magnets have practically become everyday objects. Earlier on, however, the universe consisted only of nonmagnetic elements and particles. Just how the magnetic forces came into existence has now been researched. A theoretical physicist describes a new mechanism for the magnetization of the universe even before the emergence of the first stars.
