HOW TO USE A COMPASS

Earth's Magnetic Field & How Earths magnetic field effects the compass.
Earths Magnetic Field
Recall that Earth's inner core spins faster then the outer core. This produces stream of flowing, molten iron in the outer core. But Earths magnetosphere is the magnetic field but Earths magnetic field protects Earth from cosmic rays and charged particles coming from the sun.
How Earths Magnetic Field affects the compass'
The reason why a compass works is more interesting. It turns out that you can think of the Earth as having a gigantic bar magnet buried inside. In order for the north end of the compass to point toward the North Pole, you have to assume that the buried bar magnet has its south end at the North Pole, as shown in the diagram at the right. If you think of the world this way, then you can see that the normal "opposites attract" rule of magnets would cause the north end of the compass needle to point toward the south end of the buried bar magnet. So the compass points toward the North Pole. But the Magnetic field affects the northern and southern hemisphere by the needle being magnetized and that is why the magnetic field affects the northern and southern hemisphere on a compass.
How the magnetic field works on the compass
first step into using a compass
You will need a compass, and map w/ a compass rose on it but you wouldn't really need the other thing in the picture but you can go outside. But you take the map and put find where ever you want to go but make sure it is a map with a compass on it too so you know where to look at on the compass.
Second Steps into using a compass
so you just need to know how to do the north, south, east, and west part but also remember some where relatively to some where you need to got to.
Final part on how to use a compass
Now you know how to use a compass and it's as easy like that so remember you just need a compass, and a map w/ a compass rose on it and then you know how to use A compass and know you now so if you want you can on an adventure now so do what you want to do.
