Galactic Magnetosphere: Size, Winds & Earth's Impact

[discord73]

what is the size of a galaxies magnetosphere?


Is it's size or have any relation to the size of he black hole/blackholes? or to the mass at the center of the galaxy?


Is there any kind of intergalactic wind (Like the solar wind) that interacts with a galaxies magnetosphere like our northern lights?


How strong is our galaxies magnetosphere way out here in the suburbs where the Earth is?

Galaxies typically have extremely chaotic magnetic fields. The magnetic fields are dominated by what's going on in one particular local area. You don't get one large smooth magnetic field.
