It's a hell of a lot nearer to Hudson Bay than it is to Australia.
Better Answer
It depends upon whether you are referring to the location ('Magnetic North') or the polarity (north). If you mean the location then its closer to Hudson's Bay. If you mean the polarity, then it's closer to Australia.
south
The magnetic force on Earth is called Earth's magnetic field or also the geomagnetic field.
No. Earth's magnetic field only affects earth, not other planets.
No. Earth's magnetic field does not affect its axis of rotation.
Magnetic domains have the tendency to align with magnetic fields. The Earth's magnetic field is relatively weak, but I would expect SOME alignment.
Magnetic poles
The earth as a single object has a magnetic field. If Uruguay is part of the earth, it shares the earth's magnetic field.
The Earth's magnetic field is the result of electrical currents flowing in the earth.
This is known as magnetic reversal when earth's magnetic poles change places.
The magnetic force on Earth is called Earth's magnetic field or also the geomagnetic field.
near both magnetic poles
You can't. The only thing the earth's magnetic field can tell you is the direction from where you are toward the earth's magnetic pole. That doesn't tell you anything about where you are.
Scientists believe that it is the movements in the liquid outer core that create the magnetic field. Earth's magnetic field affects the whole planet.
No
Assuming there is no Earth magnetic field, and no other significant magnetic fields, they will not allign in any preferred direction.
The nearest star to Earth is the Sun.
The Earth's magnetic field is probably caused by convective currents in Earth's interior.
If you mean the region of influence of the earth's magnetic field then its called the earth's magnetosphere
