It is the magnetic field from the north and south poles of the Earth. From the south pole straight through the center of the planet right up to Santa's house... (North pole)...
The magnetic needles of the compass align with earths magnetic field coming off the polar ice cap.
You can use a device that detects magnetism. A compass needle may suffice.
It is the magnetism, or magnetic force, of the Earth's magnetic field. Created by the movement of the planet's iron core, the magnetic field consists of roughly parallel lines connecting the North and South Magnetic Poles, which are not the same locations as the geographic poles. The magnetized compass needle (actually a very thin bar magnet) reacts to this field by lining up along a north-south axis.The north end of the needle indicates the direction to the North Magnetic Pole, allowing users to orient themselves directionally.

Compass is a device which is used to see directions previously. Compass consists of a Magnet freely suspended . A free Magnet always shows Geographical North and Geographical South. So Compass consists of a Magnet and a Aluminium pointer showing east and West direction.
It is the component of the earths magnet field which aligns the compass needle to the Magnetic North Pole. The Horizontal Component (directive force) is the greatest at the magnetic Equator (Aclinic Line), where the vertical component is the weakest. Above the magnetic north pole, it is the opposite. The Horizontal, or directive force is weakest and the vertical component is the strongest.

Magnetism. The compass aligns with the magnetic field of the Earth.
A compass is an instrument containing a freely suspended magnetic element which displays the direction of the horizontal component of the Earth's magnetic field at the point of observation.

OK- first, it is a compass. The needle of a compass is a magnet. It points to the Eath's Magnetic Poles- the two spots where the Earth's magnetic field comes out of the ground. In magnetism, opposites attract, likes repel.
The compass needle will only align itself with the magnetic meridian if it is free from all other influences except the magnetic field of earth.This is rarely so, particularly on a ship which constructed on steel. The magnetism induced in the steel by the earths magnetic field causes the compass needle to deviate from the magnetic meridian, by an amount which is called the DEVIATION.
The pull of the magnet will over ride the earths magnetism. So the compass will react to the magnet as it passes through its field.
Leafcutter ants have an "inner compass" to navigate. It uses magnetic poles to find its way.
