Why are the magnetic poles and the geographic poles of the earth not in the same place?

No, it can but it doesn't necessarily need a variable.
I have no idea what the previous answer means. The earth spins on its axis. The spin axis provide the geographic north and south poles.
On the other hand the earth's magnetism does not work like a bar magnet. Instead, the iron and cobalt core spins at a slightly faster rate than the rest of the earth. This sets up eddy electrical currents which creates magnetic fields. In the northern hemisphere, the magnetic fields join under Northern Canada.

Is earth's magnetic poles and its geographic poles are in the same place?
no
What is true about earths poles?
Only the magnetic poles wanderD.Earth's magnetic and geographic poles are generally not in the same place.Geographic poles are defined by Earth's rotation.
Why don't the Earth's geographic poles coincide with the magnetic poles?
because of core of our earth.
What is true of Earth's poles?
Earths magnetic and geographic poles are generally not in the same place
True or false the magnetic poles are not located exactly at the geographic poles?
True. The magnetic poles move constantly.

Who invented poles?
There are two types of global poles; magnetic and geographic. Neither were invented. The magnetic poles are two points on the Earth where the magnetic field is most intense. The geographic poles are the northernmost and southernmost positions on the globe.
What is true of Earth's poles?
Earths magnetic and geographic poles are generally not in the same place
What point or place do cosmic particles end up when they follow the lines of the Earth's magnetic field?
To the magnetic poles, which are offset somewhat from the geographic poles, and slowly change location.
What statement is true about Earth's poles?
Only the magnetic poles wanderD.Earth's magnetic and geographic poles are generally not in the same place.Geographic poles are defined by Earth's rotation.
When using a compass to map an area why is it important to know an areas magnetic declination?
Unlike the geographic poles, which are always in the same place, the magnetic poles change location throughout the history of earth. So when using a compass to map or explore the Earth's surface, you need to make a correction for the difference between geographic nor and magnetic north.
What is the meaning of pole when describing earth?
Earth has two pairs of poles, the geographic north and south poles and the magnetic north and south poles. The geographic poles are the two places where Earth's rotational axis, the imaginary line that represents the center of Earth's rotation, intersects the surface of the earth. The magnetic poles are where Earth's magnetic field diverges/converges, just like the poles of a bar magnet, except that Earth's north magnetic pole is comparable to the south pole of a bar magnet, and Earth's south pole is comparable to the north pole of a bar magnet. The locations of the geographic poles never change, but the magnetic poles wander around from time to time. In fact when studying the floor of the Atlantic Ocean for the first time scientists found evidence that the polarity of Earth's magnetic field completely reverses every few hundred millennia (the north and south magnetic poles switch places).
Why does a compass does not show exact geographical poles?
A compass needle points to the magnetic poles, which are not the same as the geographic poles. There is nothing special about the magnetic field at the geographic poles.
What is magnetic variation?
Since the Earth's magnetic poles are not located at the geographic poles, a magnetic compass doesn't point to 'true' (geographic) north. The DIFFERENCE angle between magnetic north and true north is the magnetic variation or declination where you are. It changes for different locations.
True or false the magnetic poles are not located exactly at the geographic poles?
True. The magnetic poles move constantly.
