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.
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.
The geographic north pole behaves as a magnetic south pole because opposite magnetic poles attract each other. This means that the north-seeking pole of a compass needle (which is used to determine direction) points toward the magnetic north pole, which is near the geographic north pole. Thus, the geographic north pole is essentially a magnetic south pole in terms of magnetism.
B
No. The compass needle points toward the magnetic north pole.
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 Poles are fixed at the earth's axis of rotation. The Magnetic Poles are located within a few hundred kilometres, but wander. The magnetic polarity of Magnetic North (the location) is south, which is why it attracts the north pole of a compass needle.
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 northernmost point on Earth is the geographic North Pole. It is located at 90 degrees latitude north.
No. The magnetic pole wanders quite a bit - even towards the south rotational pole at times.

The North pole of a magnet or Earth attracts the South pole, while repelling the North pole. The South pole attracts the North pole and repels the South pole. For Earth, the North magnetic pole is located near the geographic North pole, and the South magnetic pole is near the geographic South pole.
the magnetic north pole moves while the geographic north pole stays in the same place
