Many things are now forgotten. Horses and jobs are gradually disappearing, and more and more objects with specific uses are disappearing. Among them, what I’m curious about today is a thing called a compass.
Actually, I had this thought today. Do children born these days know what a compass is used for? Maybe you learn at school? But maybe you don’t know how to write. It’s probably because these days, you don’t have to look for an area with your cell phone and know where it is in the north, south, east, west, or west.
However, if you are a person who likes trivial knowledge like me, I thought it would be useful information, so I organized it. 나침반 보는법
How to read a compass is simple 좋은뉴스
There are some things you need to know before looking at the compass. All compasses have English initials N, S, E, W written in four directions. As many of you know, this means east, west, south, and north.
N – North
S – South
E – East
W – west
You just need to know this. Of course, each product is different, but between them is written northeast, northwest, southeast, southwest, which contains such a simple meaning between north and east.
If you know what these initials mean, then there’s what you need to do. The point is that you have to look at the compass on a flat surface. If you matched the flat, you can adjust it so that the red needle is facing north. Then, the direction you are looking at is the left side you are standing at, the right side is the east side, and the back side is the south side.
how about it? Simple, right? Then, if you are curious about how the compass works, please read a little more.
principle of the compass
It is believed to have been first made in ancient China, it is made of lodestone and scooped and placed on a flat surface. Then, it can be rotated by the earth’s magnetic field. To put it simply, if you place a very light bar magnet flat, the n-pole rotates toward the north and the s-pole toward the south.
However, the Earth’s rotational axis and magnetomagnetic axis differ by about 11 degrees, so it does not exactly point to the North Pole as we know it. However, it is possible to know the location of the north, south, east, west, and west, although not exactly.
Today, we learned how to use a compass and how it works. It seems like it’s hard to express in writing.. I hope this helps.
