Do galaxies have magnetic poles?
Each galaxy does have a natural magnetic field, but it is weak. The magnetic field of our galaxy is about 100 times weaker than the magnetic field of the earth. The magnetic field of a galaxy has two basic components: a large-scale ordered pattern that mimics the shape of the galaxy, and a small-scale random pattern.
Do galaxies have poles?
Galactic latitude is positive towards the north galactic pole, with a plane passing through the Sun and parallel to the galactic equator being 0°, whilst the poles are ±90°….Definition.

Are there magnetic fields in space?
Cosmic magnetism spans an enormous range in its strength, varying by a factor of a hundred billion billion between the weak magnetic fields in interstellar space and the extreme magnetism found on the surface of collapsed stars.
Does our galaxy have a magnetic field?
The Milky Way galaxy has its own magnetic field. It’s extremely weak compared to Earth’s; thousands of times weaker, in fact. But astronomers want to know more about it because of what it can tell us about star formation, cosmic rays, and a host of other astrophysical processes.
Is the Milky Way a plane?
The plane of the Milky Way is the flat part containing most of the galaxy’s stars. Our sun lies slightly off-center in the galactic plane.
Is Milky Way in one plane?
The galactic plane is the plane on which the majority of a disk-shaped galaxy’s mass lies. In actual usage, the terms galactic plane and galactic poles usually refer specifically to the plane and poles of the Milky Way, in which Planet Earth is located.
Why do galaxies have magnetic fields?
In short, the theory describes how an internal (to the galaxy) dynamo creates the magnetic field by a fluid-like motion – rotation and convection – in hot gas so that kinetic energy (energy due to motion) converts into magnetic energy. A distant galaxy’s internal dynamo might be fuelled by supernova explosions.
