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).
true north is the direction towards the Geographic north pole, the point on the globe exactly 90 degrees north of the equator, and thru which the earth's rotational axis meets the surface. Magnetic north is the direction towards the magnetic north pole which is predicted* to be located at 82.7 degrees north latitude, and 114.4 degrees west longitude (just north of Canada). Magnetic north is where a compass actually points to, so you must adjust your compass acordingly. *this is predicted because magnetic drift causes the pole to move from year to year.
"IF Earth's magnetic north pole is not located at the geographic north pole why is a compass useful for determining direction?"
no, the magnetic north pole is determined by the molten iron core, and changes.
An ordinary magnetic compass points to magnetic north, not to true north. If the difference between the two directions is large and not accounted for, you can get lost.

The magnetic north is in a generally northerlydirection.
It is not! Geographic North Pole is in the Arctic!
Earths geographic North Pole is also currently a magnetic north pole. This is however not always the case because over geological time scales the Earth's magnetic poles flip as a result of changes of flow in Earth's molten core which produces Earth's magnetic field.
The compass needle aligns to the Earth's magnetic field. This magnetic field is not exactly aligned with the Earth's rotation, but the magnetic south pole is close enough to the geographic north pole for the compass to be useful in most places.
the geographic north pole True North is geographic north as opposed to magnetic north. Since a compass uses magnetism to find North, the North that it finds is the magnetic North.
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.
Actually, a compass points to the magnetic north pole, not the geographic north pole.
No. If you are talking about magnetic compasses, they are aligned with the Earth's magnetic field, which is not exactly north-south (depending where on the Earth you are located). There are, however, special compasses that make use of the Earth's rotation; those will point north-south, regardless of the magnetic field.No. If you are talking about magnetic compasses, they are aligned with the Earth's magnetic field, which is not exactly north-south (depending where on the Earth you are located).

true north is the direction towards the Geographic north pole, the point on the globe exactly 90 degrees north of the equator, and thru which the earth's rotational axis meets the surface.

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