Does the Milky Way galaxy have a magnetic field?

Well does it ?...what about an equator ?

If it does have a magnetic field , would it have a north and south pole too then?

There are magnetic fields on a galactic scale.  They are quite small when compared with the earth's magnetic field but do represent large quantities of energy because of the vast scale over which they operate.  They are quite difficult to observe and I don't think that it is known yet if they have any overall coherent structure on the scale of the whole galaxy or are just associated with clouds and turbulence in the spiral arms.

That reply was from memory but seems to be ok because Googling  "Galactic magnetic field"  will give you lots more detailed information

Perhaps, I wonder, then ,that the Universe itself might have a magnetic field ?...or is that a simple yes, no or don't know, or will never know.. ?

(o) this sybal represents the earth and it's magnetic feild. the circle as u can c is the Earth. the curves around it are the magnetic feild. as u can c the magnetic feild curves tward the north os south poles. when a solar flare goes tward the earth it gets stoped dead in it's trackes cause of the magnetic feild. the magnetic feild the brings it down tward the north or south pole creating the phenomenon known as the norther or souther lights.
