Subject: Does the universe have a magnetic field?

If galaxies and super clusters have magnetic fields, would the universe have a magnetic field as well?

Yes, it has all of them.

You’re asking good questions. My knee jerk reaction is “no”, because a magnetic field requires an electric charge and a rotation. The universe has no net electric charge and no net rotation.

But I could be wrong.

On the other hand, that just shows that the universe has no dipole magnetic field. Could it have quadrupole, octopole etc. fields? Not of any great strength. But look at the CMBR, there is a small quadrupole variation in the CMBR that is aligned with the octopole variation.
