What are compasses used for?
Compasses are useful for taking bearings and for orienting the map so that it is aligned with the terrain – but it is possible, in most areas, to complete a course quite easily and efficiently without a compass (an exception: it would be difficult to navigate flat areas poor in prominent features without a compass).
What is a compass used for?
The compass is generally used to run a traverse line. The compass calculates bearings of lines with respect to the magnetic needle. The included angles can then easily be calculated using suitable formulas in case of clockwise and anti-clockwise traverse respectively.

Why would a needle point to the south pole?
If you were using a compass 800,000 years ago and facing north, the needle would point to the south magnetic pole. Why? Even though the Earth acts like a giant magnet, it is not stable. Both the north and south magnetic poles are slowly shifting. Since the magnetic north pole was discovered in the early 19th century, it has drifted northward by more than 966 kilometers (600 miles) and it continues to move about 40 miles per year. The north and south magnetic poles have also switched places many times in the Earth’s history.
How does a magnetic compass work?
While the design and construction of this type of compass has changed significant ly over the centuries, the concept of how it works has remained the same. Magnetic compasses consist of a magnetized needle that is allowed to rotate so it lines up with the Earth's magnetic field.

How to align a compass arrow?
Line up the edge of your compass on this line so that the travel arrow is in the direction you wish to travel, then twist the azimuth ring (which is simply the ring with the measured units of degrees on a compass) until north on the map and the orienting arrow are aligned.
Does the red needle stay on the magnetic north?
No matter which way you turn the compass, the red needle stays fixed on magnetic north. However, the second thing to know when working with a compass is that magnetic north is NOT true north (the North Pole).
How to use a compass and map?
Here is how to use the map and the compass together. First, check where you’re currently facing or traveling. Put the compass on your palm and watch the magnetic needle. The needle should swing off to sides, unless you are facing North.

How to Use a Compass to Plot Bearings in the Field
If you’ve taken a bearing (or found a course) from a topo map, you can steer yourself along with it by holding the compass level, then turning your body so that the needle’s boxed by the orienting arrow. When that happens, you’re facing your destination with the direction-of-travel arrow pointing the way to go.
Use a Compass to Plot Bearings on a Map
You can also plot a known compass bearing on the map—the reverse process. This may arise when you don’t know your current position but have taken a back bearing from a visible landmark you can identify on the map. Turn the compass dial so that the bearing intersects the index line.
How does a compass work?
A compass works by detecting the Earth’s natural magnetic fields. The Earth has an iron core that is part liquid and part solid crystal due to gravitational pressure. It is believed that movement in the liquid outer core is what produces the Earth’s magnetic field.
When did the compass come into use?
The compass later came into common use in the west during the 14th century AD. This led to what is now known as the Age of Exploration where major European powers started further exploration of the World including North and South America.
What is a compass magnet?
Essentially a compass is a light weight magnet, generally a magnetized needle, on a free rotating pivot. This allows the needle to better react to nearby magnetic fields. Since opposites attract the southern pole of the needle is attracted to the Earth’s natural magnetic north pole. This is how navigators are able to discern north.
