Magnets and magnetism is something most take granted, these are common objects and effects. But the early Universe was much different, consisting on non-magnetic elements and particles how would this force come into being?
From a paper by Dr. Reinhard Schlickeiser at the Institute of Theoretical Physics of the Ruhr-Universitat Bochum:
"Before the formation of the first stars, the luminous matter consisted only of a fully ionised gas of protons, electrons, helium nuclei and lithium nuclei which were produced during the Big Bang.
"All higher metals, for example, magnetic iron could, according to today's conception, only be formed in the inside of stars", says Reinhard Schlickeiser.
"In early times therefore, there were no permanent magnets in the Universe."
The parameters that describe the state of a gas are, however, not constant. Density and pressure, as well as electric and magnetic fields fluctuate around certain mean values.
As a result of this fluctuation, at certain points in the plasma weak magnetic fields formed - so-called random fields. How strong these fields are in a fully ionised plasma of protons and electrons, has now been calculated by Prof. Schlickeiser, specifically for the gas densities and temperatures that occurred in the plasmas of the early universe"
