Introduction of Magnetic Material Ndfeb Used by Magnetic Badge
The magnet badge is a new type of badge. The ordinary badge products will damage the clothes and stimulate the skin, but the magnet badge can prevent these problems by using the magnetic principle. It is fixed on both sides of clothes through the principle of magnetic block attraction. It's strong and safe. The service life of the product will also be greatly extended by changing the label quickly.
Ⅰ. The magnetic material of the badge magnet
Magnetic material used for the badge magnet is NdFeB, which many people may not have heard of. Little is known about its content. Here is some information about this magnetic material.
The material is an important basis of social progress, an essential indicator of human progress and a milestone of social progress. Throughout the history of human development, we will find that the discovery and widespread use of new materials have improved the human ability to transform nature to a new level.
The neodymium iron boron magnetic material, one of the functional materials of the badge magnet, was used as early as the 3rd century BC. At that time, Sinan was made of natural magnetite. The compass was made of steel needle magnetization in the Song Dynasty, which provided the critical technology for the development of navigation.
The nd-Fe-B ferromagnetism is an essential functional material. It has been widely used in transportation, energy, machinery, computers, household appliances, microwave communication, instrument technology, electrical engineering, automation technology, automobile industry, petrochemical industry and biology.
In engineering and other fields, the magnet application has become one of the important indicators to measure a country's comprehensive national strength and economic development level. It is also one of the foundations of the current litigation industry.
Some people compare the invention and application of the semiconductor integrated circuit with the modern information industry. Then, the application of the NdFeB magnet provides a powerful leap for the current information industry.
Ⅱ. Methods and skills of using the badge magnet
With the rapid development of economy, the pace of the industrialization of the magnetic badge is faster and faster, and all fields are developing rapidly. Strong magnets are more and more widely used in the industry, manufacturing and electronics.
First of all, we must understand that strong magnets are easy to break. Because the nature of the strong magnet is very fragile, it is easy to break when it falls on the ground.
Therefore, please be careful not to use strong methods such as tension when using the badge magnet. The reason is that the strong magnet is very fragile and easy to cause damage.
Third, when storing the powerful magnets, they should be stored according to the different shapes of the powerful magnets. The permanent magnet NdFeB badge magnets must be placed in pairs if the strip magnets are used. To prevent the magnet from losing its magnetism, it is necessary to lean the N pole of one magnet against the S pole of the other magnet.
Strong magnets are widely used. Some magnetic treatments use the magnetism of strong magnets. As we all know, in recent years, the maglev trains and the colour plastic magnetic pushpins have applied the principle of magnets.
Nuclear magnetic resonance is an essential means and method for people to check their bodies. It uses powerful magnets. We need to know some practical skills about other electroacoustics, electromagnetic relays, etc. we can't cause damage and unnecessary loss when using powerful magnets.
