I was wondering what is the source of the magnetic field of our galaxy. Is it possible that such source could be the super massive black hole in the center of the galaxy?
Regards.

The quasar is powered by an accretion disc around the black hole.
The source of the Milky Way's magnetic field is believed to be a combination of electrically charged particles in motion and the rotation of the galaxy itself. As the galaxy spins, it generates a dynamo effect that amplifies the magnetic field.
The strength of the Milky Way's magnetic field varies throughout the galaxy, but on average it is estimated to be about 10-6 Gauss, which is relatively weak compared to other spiral galaxies.
Yes, the Milky Way's magnetic field does have an effect on Earth's magnetic field. However, the strength of the Milky Way's field is much weaker than Earth's, so it does not have a significant impact on our daily lives.
The Milky Way's magnetic field is studied through a combination of observations and simulations. Astronomers use telescopes to measure the polarization of light from celestial objects, which can provide information about the strength and direction of the magnetic field. Computer simulations are also used to model and understand the behavior of the magnetic field.
Yes, the Milky Way's magnetic field can change over time. The strength and direction of the magnetic field can be influenced by various factors such as the movement of gas and stars within the galaxy, as well as interactions with other galaxies. However, these changes occur on a very slow timescale, so they are not easily observable in human lifetimes.
