If You Are Lost In A Forest, Use Magnetism

Most people know that the compass is used to navigate yourself around. However most don't know how it works. A compass is a magnet that is free to line up with magnetic field lines. The earth is basically a giant magnet with a north and south pole. However, the north pole of a compass is attracted to the geographic north pole of the earth.. therefore the geographic north pole of the earth is a magnetic south pole. The compass is able to navigate you around earth when you are lost because of magnetic field lines which run from north to south outside of the magnet. A north point of a compass will point towards wherever the magnetic field lines point. A compass is a good thing to bring with you when you travel or hike because it doesn't require electricity and the poles on earth will most likely never change, making the compass a consistent tool to have for an emergency. A compass is polarized which means it has two distinct and opposite ends. Regardless of where you are on earth, if you have a compass you can use magnetism to help you find your way back home!
