Why is the universe magnetized? It's a question scientists have been asking for decades. Now, an international team of researchers including a University of Michigan professor have demonstrated that it could have happened spontaneously, as the prevailing theory suggests.
The findings are published in the Jan. 26 edition of Nature. Oxford University scientists led the research. "According to our previous understanding, any magnetic field that had been made ought to have gone away by now," said Paul Drake, the Henry S. Carhart Collegiate Professor of Atmospheric, Oceanic, and Space Sciences and a professor in physics at U-M. "We didn't understand what mechanism might create a magnetic field, and even if it happened, we didn't understand why the magnetic field is still there. "It has been a very enduring mystery." With high-energy pulsed lasers in a French laboratory, the researchers created certain conditions analogous to those in the early universe when galaxies were forming.
Through their experiment, they demonstrated that the theory known as the Biermann battery process is likely correct. Discovered by a German astronomer in1950, the Biermann process predicts that a magnetic field can spring up spontaneously from nothing more than the motion of charged particles. Plasma, or charged particle gas, is abundant in space. Scientists believe that large clouds of gas collapsing into galaxies sent elliptically shaped bubbles of shockwaves through the early universe, touching off flows of electric current in the plasma of the intergalactic medium.
Anyone who has built an electromagnet in middle school science class is familiar with this concept, Drake said. "If you can make current flow, you make a magnetic field," Drake said. The question in astrophysics was what could have generated the current. This experiment demonstrated that such asymmetrical shockwaves could do the job. The results, Drake said, aren't particularly surprising. But it's important for scientists to test their theories with experiments. "These results help strengthen the understanding that we've taken from our interpretation of astrophysical data," Drake said. "And understanding the universe and most definitely the origin of life is one of the great human intellectual quests."

History
Before the 1970s, physicists were uncertain about the binding mechanism of the atomic nucleus. It was known that the nucleus was composed of protons and neutrons and that protons possessed positive electric charge while neutrons were electrically neutral. However, these facts seemed to contradict one another. By physical understanding at that time, positive charges would repel one another and the nucleus should therefore fly apart. However, this was never observed. New physics was needed to explain this phenomenon.
A stronger attractive force was postulated to explain how the atomic nucleus was bound together despite the protons' mutual electromagnetic repulsion. This hypothesized force was called the strong force, which was believed to be a fundamental force that acted on the nucleons (the protons and neutrons that make up the nucleus). Experiments suggested that this force bound protons and neutrons together with equal strength.
It was later discovered that protons and neutrons were not fundamental particles, but were made up of constituent particles called quarks. The strong attraction between nucleons was the side-effect of a more fundamental force that bound the quarks together in the protons and neutrons. The theory of quantum chromodynamics explains that quarks carry what is called a color charge, although it has no relation to visible color.[3] Quarks with unlike color charge attract one another as a result of the strong interaction, which is mediated by particles called gluons.

Where is gravity mentioned? I only see types of charges in what you posted. You can't be suggesting that the strong force is gravity!
Actually, until you and those who proffer charge as an attractive/repellant field, explain what it is, you are really no more accurate than those who throw out gravity as a cause. Effects are not an explanation!
And throwing in speculative quarks and gluons only muddies up the mix.
By definition, there can be no electricity/magnetism at the subatomic level, unless there are charged particles, and those need to be explained, not just proclaimed. Until then, effects can be observed, but they do not explain what is happening and why.

“The options were a quasar-like outburst from the black hole at the Galactic Centre, or star-power — the hot winds from young stars, and exploding stars,” said Dr. Gianni Bernardi of the Harvard-Smithsonian Center for Astrophysics, in a statement. “Our observations tell us it’s star-power.”
