Magnetization method of magnetic needle of compass

The magnetizing method of the magnetic needle of the compass is: place the compass horizontally, adjust the meridian direction first, and then place large magnets at both ends of the meridian direction. The positive and negative poles are opposite, so that the magnetic needle is placed in the magnetization space. Generally, it can be placed for five to seven days, which can achieve a good magnetization effect.

Compass actually uses the principle of compass positioning: the earth is a big magnet, its geomagnetic south pole is near the geographical north pole, and the geomagnetic north pole is near the geographical south pole. The needle of a compass is actually a needle magnet. Under the magnetic force of the earth's magnetic field, one end of the compass will be guided and the other end will point to the north.

The magnetic needle on the compass is generally made of permanent magnet material, but if it is used for too long, or the place where it is placed is affected by high temperature, violent vibration or strong magnetic field, the magnetic needle will weaken. At this time, the magnetic needle is very insensitive or inaccurate. The magnetic needle needs to be magnetized, and the polarity must be paid attention to when magnetizing, and it cannot be reversed.

Practical application of compass

Most people think that the main function of compass is only to look at the house. After testing, the compass has many other important feng shui functions:

1, soothe the nerves: put the compass under a thick pillow, which can play the role of town house, ward off evil spirits and soothe the nerves, so that you can have a good sleep and rest assured that it will not be crushed. However, it is only useful to put the compass on a pillow made of buckwheat skin, such as a pillow made of cloth, hemp and cotton, and the effect is not good.

2. Peach Blossom: Hold the compass vertically and let the horizontal oil run to the top. On the full moon night of 15th and 16th, hold it at a 30-degree angle, thinking only of the word "Geely", and say to the moon, "Love, love, please come quickly." Soon, love comes to you. This is the biggest tool to promote peach blossom, which means "the sun and the moon are one". The compass is the sun, and the full moon is the moon, but it must be the full moon, that is, the round edge is in place and the sun and the moon shine together. If it's the first quarter, most people are grumpy, while the second quarter is depressed.
