How a compass works
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 and the north pole has the most strength. So that is how a compass works.
All over the world there are compasses but this compass is a military compass it is used just like any other compass. The only difference is the way it looks and the per-pus of the compass.
This compass is used mainly for diving deep underwater. It helps the people that are using it to find their way back to their boat.
This compass is just any ordinary compass it helps people find their way through the woods or any other place you may need it.
