Its needle is a fine bar-magnet on a low-friction pivot to allow it to align itself with the Earth's magnetic field.
Its North is therefore the Earth's magnetic, not rotational, North Pole, so a correction has to be made to the reading to establish the true geographical bearing. Since the magnetic pole slowly precesses over the years, the correction varies with time.

Will a compass work on an aluminum boat?
Yes, a compass will work on an aluminum boat as long as there are no strong magnetic interferences nearby that could affect its accuracy. Aluminum itself does not interfere with the function of a compass.
How do nautical compasses work?
Nautical compasses work based on the Earth's magnetic field. The compass needle aligns itself with the magnetic field lines, indicating the north-south direction. The compass rose on the compass card provides reference points for navigation.
How can you fix a compass that is next to a magnet?
To fix a compass near a magnet, move the compass away from the magnet to ensure accurate readings. If that doesn't work, try demagnetizing the compass by rubbing a strong magnet in the opposite direction. Finally, calibrate the compass according to manufacturer instructions to reset its accuracy.
Why does a compass always work?
A compass works by aligning itself with the Earth's magnetic field. The needle of the compass is magnetized, pointing towards the magnetic north pole. As long as the Earth's magnetic field remains stable and the compass is not influenced by nearby magnetic objects, it will always point north.
What kind of force allows a navigation compass to work?
A navigation compass works based on the force of Earth's magnetic field. The compass needle is magnetized and aligns itself with the magnetic field, pointing towards the magnetic North Pole.
