The outdoor compass is a simple instrument for distinguishing the orientation. The predecessor of the compass is Sinan, one of the four great inventions of ancient China. So have you ever heard of the compass? What is the difference between the compass and the compass? Next hundred safety net give you a detailed analysis, please read the following carefully.
The difference between the compass and the compass is summarized as follows.
The North needle is a kind of tool used to indicate the direction, which is widely used in the interpretation of various directions, such as navigation, field exploration, urban road map reading and other fields. It is also an indispensable tool for mountaineering exploration. The basic function is to use the effect of the earth's magnetic field to indicate the north direction. It must look for a relative position with the map in order to understand its position. Like the compass, the north pole of the magnetic needle points to the geographical North Pole, which can be used to identify directions. But in some parts of the world, compass is also called compass. There are many patterns in the compass. This article will describe how to use the compass orientation according to the most widely used transparent floor compass which is the most widely used of the hike.
The predecessor of the compass is Sinan, one of the four great inventions of ancient China. The main component is a magnetic needle which can be rotated freely on the shaft. The magnetic needle can be kept in the tangent direction of the magnetic meridian under the action of the geomagnetic field. The north pole of the magnetic needle points to the geographical Antarctic, which can be used to identify directions. It is often used in navigation, geodesy, travel and military affairs. The invention of the compass is the result of the understanding of the object's magnetism in the long term practice of our working people. Because of production labor, people began to understand magnetic properties by contacting magnetite. It was first found that the magnetic properties of magnetite were found. Later, the directivity of the magnets was found. After many experiments and researches, a practical compass was finally invented.
In fact, the two heads are pointing south and north respectively. If the length of the two needles is the same, it is mainly to see which side of the red needle, the guide is called the compass, and the north is called the compass. The difference between compass and compass is mainly the different way of calling, and the two functions are the same.
