It is believed that the earth's magnetic field is due to the dynamo effect within the nickel-iron core of the earth. The core is molten, a dense and highly compressed fluid. The physics must be well awesome. Anyway, the nature of a fluid is that it is has some mobility. And there is movement within the fluid core of the earth which will, therefore, cause the recorded shift in the location of the magnetic poles on the mantle of the earth.
Recall that the mantle of the earth, the tectonic plates and such, is actually "floating" on the liquid core.
Yes. the magnetic North Pole has now been proven to move 40 miles towards Russia every year. This has caused airports to re-calibrate runways to correspond with airplane compasses and directional apparatus.
The magnetic north pole was in Canada's Northwest Territories for most of the last 400 years. However, since 2001 it has been moving further north. In 2010 it is at 72.21°W longitude, 80.08°N latitude. The Canadian Natural Resources page states that the pole moves around by as much as 85 km within any given day and the position is wandering towards Russia by about 60 km per year.

geographical north pole where meridians of longitude meet does not move.....though magnetic north does.
yes because all the ice in the ice land and the geographic south pole is melting so the geographic south pole is moving im a very very curtain.
Of course it does very from year to year but in the past 10 years It is moved about 40 feet per year
North East, at about 40 K / year
The north pole of the magnet points down.
long long way to go
They are not.In 2015, the magnetic north pole is about 255 miles from the geographic north pole,and is moving toward Russia at about 35 miles per year.The south magnetic pole is even more weird. That one is about 1,780 miles from thegeographic south pole, and moving northwest at about 20 miles per year.Notice that the north and south magnetic poles are NOT directly opposite each otheron the Earth's surface.
"IF Earth's magnetic north pole is not located at the geographic north pole why is a compass useful for determining direction?"
By dancing at the north pole, idiot
No and no. The Magnetic north pole is currently in North America. The geographic north pole is over water which is frozen quite thick. So people can walk to the geographic north pole and it has also been visited by several submarines.
The geographic north pole is the location of the earth's axis in the northern hemisphere. It differs from the magnetic north pole by a few degrees. The geographic north pole is static and unchanging. The magnetic north pole moves based on the earths core (about 40 miles per year).
It is not! Geographic North Pole is in the Arctic!
The exact diameter of the geographic north pole (like the south pole) is in theory zero.

the pole of the compass is attracted to the earths geographic north pole

No. The magnetic pole wanders quite a bit - even towards the south rotational pole at times.

the magnetic north pole moves while the geographic north pole stays in the same place
The geographic North Pole is the northermost point on the globe.
no, the magnetic north pole is determined by the molten iron core, and changes.
