Giant magnetic fields in the universe

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.

Linearly polarized relics were found in the four galaxy clusters observed, in one case for the first time. The magnetic fields are of similar strength as in our Milky Way, while the measured degrees of polarization of up to 50% are exceptionally high, indicating that the emission originates in an extremely ordered magnetic field. “We discovered the so far largest ordered magnetic fields in the universe, extending over 5-6 million light years”

Do galaxies have magnetic fields?

Would a galaxy cluster have magnetic field?

Yes. Galaxies have magnetic fields, it’s the magnetic fields of the Milky Way that randomise the approach directions of all cosmic rays that come from outside the solar system, apart from the very strongest cosmic rays.

It never occurred to me that a galaxy cluster might have a magnetic field. The OP suggests that it does.

Every atomic particle that has a charge has a magnetic field. This includes protons, electrons and alpha rays.

Maybe Galactic Filaments have magnetic fields as well, which would suggest a lot of interaction is going on.

I don’t understand the origins of galactic scale magnetic fields. From the information in the OP, they seem to have something to do with the collision of hydrogen gas clouds at high speeds.

What would be the safe distance for human life from such a source?
