In the case of an unclear magnetic field, can you use a compass to discern the direction 5

No, because if there is a strong magnetic field nearby, the compass will be deflected at an angle without pointing due north. I have done experiments, the host of the computer is a strong magnetic field source, I put the compass next to the main unit (up and down, left and right back and forth, some places the magnetic field is strong, some places the magnetic field is weaker), the compass will keep rotating. You can also give it a try.

No. There is a magnetic field around the magnet and around the energized conductor, which can be checked with a small magnetic needle. In general, the small magnetic needle is pointing to the south and north, and if the direction of the small magnetic needle changes suddenly, there must be other magnetic fields around the small magnetic needle.

2) The direction of the magnetic field The magnetic field is directional, when the small magnetic needle is placed at different points of the magnetic field, the direction of the n pole of the small magnetic needle is different, which means that the direction of the magnetic field is different. We stipulate that at a certain point in the magnetic field, when the small magnetic needle is at rest, the direction in which the north pole points is the direction of the magnetic field at that point.

3) The nature of the magnetic field The basic property of the magnetic field is that it produces a magnetic force on the magnet placed in it, and the interaction between the magnets is generated by the magnetic field. The small magnetic needle placed in the magnetic field can be deflected because the magnetic needle is affected by the magnetic field. Although the magnetic field cannot be seen or touched, we can perceive and recognize it according to its effect on the magnet placed in it.

No. There will be other magnetic field interference.

Hopefully the computer upstairs will rot.

The fact that the compass always points in a north-south direction also illustrates the existence of the Earth's magnetic field. But generally speaking, the geomagnetic field is relatively weak, and its strength is only 1/10,000 of the magnetic field strength of a common permanent magnet. According to the principle of opposites magnetically attracting, the south pole of the compass should point to the north pole of the geomagnetic field, and the north pole of the compass should point to the south pole of the geomagnetic field.

It can be seen that the south pole of the geomagnetic field is located near the north pole of the earth; Whereas, the north pole of the geomagnetic field is located near the south pole of the earth.

A compass can also be used to discern east-west directions.

A compass is an instrument that uses a magnetic needle that can be rotated to determine direction. Due to the geomagnetic field, one end of the needle is roughly pointing south, and this property allows you to distinguish the direction.

When facing the north pointed by the compass, facing north and facing south, left west and right east. That is, on the left hand side is the West, and on the right hand side is the East.

Of course not! You have the north and south directions, can't you find things yet?

You just need to face your south, spread your limbs, and your left hand is east and your right hand is west.

The compass is able to point the way because it is subjected to the force of the geomagnetic field, and when it is stationary, the south pole of the magnetic needle always points to the south of the geographical location

Therefore, the answer to slow grinding is: south

1. Compass. The direction of the compass arrow is the south, and the opposite direction is the north rift.

2. Look at the direction of the sun. The position of Xinyang in different periods of time is also different, and the direction can be judged by the position of the sun and the intensity of the light.

3. The annual rings of trees. If there happens to be a tree stump nearby, the tree's growth rings are also one of the important ways to determine the direction. Because of the light, the south-facing part of the rings will be wider, and the north-facing part of the rings will be denser.

4. If it happens to be in a dense forest, and there is no stump to refer to. Well, you can identify the direction based on the ant burrow, because the ant's burrow is mostly oriented south.

5. If there is no ant burrow, then the canopy is also a very good reference. There will be a clear difference between the north and the south of the trees that are more luxuriant, and the trees in the north are more sparse.

6. If it is a starry night, the side wheel can identify the direction according to the stars, the specific method is: first find the Big Dipper in the sky, along its "spoon handle", find the sixth and seventh stars, according to the mathematical principle of determining a straight line at two points, connect the two stars into a straight line, just indicate the direction from south to north.

Summary. Hello, dear, happy to answer your questions. White refers to the fact that both ends of the needle in the southern compass are generally dyed red and white, and the red end is often pointed north, so we can conclude that the white end of the compass points to the south.

When the magnetic needle of the compass is stationary, the white end of the magnetic needle points in that direction.

Hello, dear, happy to answer your questions. White refers to the south refers to the south and the two ends of the needle are generally dyed red and white, of which the red end is often pointed to the north, so we can conclude that the blue end of the compass points to the south.

Expansion: The compass is a tool used to identify the bearing, it can rotate freely under the action of the magnetic field, so as to maintain a land-like direction to return to the core, so it is widely used in geodesy, navigation, travel and other work.

The compass, called Sinan in ancient times, is mainly composed of a magnetic needle mounted on the shaft, the magnetic needle can rotate freely under the action of the natural geomagnetic field and remain in the tangent direction of the magnetic meridian, the north pole of the magnetic needle points to the north magnetic pole, and the direction can be identified by using this performance.

The earth is a big magnet. The two poles of the Earth are close to the geographic south pole and the geographic north pole, respectively. When the magnet on the earth's surface can rotate freely, it will indicate north and south due to the nature of the magnet that repels the same sex and attracts the opposite sex.

yes, why is it wrong upstairs?

The traditional compass is a magnetic pointer, which uses the principle of opposite-sex attraction to check the direction of the geomagnetic field and indicate the north and south.

The phone's digital compass is two magnetic field sensors that detect the direction of the magnetic field in the plane and then display it on the software interface.

A compass is an instrument that uses a magnet to indicate direction.

Summary. Dear dear, it's a pleasure to answer your <>

The direction in which the magnetic needle north pole points is the direction of the magnetic inductance line. Magnetic inductance lines refer to the direction in the magnetic field, symbolizing the strength, direction, and composition of the magnetic field. A magnetic needle refers to a rectangular magnet whose response to the magnetic field is affected by the direction of the magnetic field, causing the magnetic needle to rotate so that the tip of the needle points to the geographic north pole position in the opposite direction of the earth's magnetic field.

However, since the direction of the Earth's magnetic field lines is constantly changing around the geographic magnetic poles, the pointing of the magnetic needle will deviate to varying degrees, which is the error of a conventional compass**.

Is the direction of the magnetic needle's north pole the direction of the magnetic inductance line? Isn't the traditional compass wrong?

In order to reduce the error, the traditional compass is generally used with the verification and correction adjustment and other auxiliary tools. Now, with the help of advanced technology, a more accurate magnetic inductance line detection and correction instrument has been designed, which can more accurately measure the direction and intensity of magnetic inductance lines, and further improve the accuracy of magnetic needle and compass correction.
