What industry does the powerful neodymium iron boron magnet affect?

1. From the analysis of the principle of magnetic field formation of powerful neodymium iron boron magnets

Powerful neodymium iron boron magnets are the same as electricity, invisible and insensible, only when the iron is close will the magnetic force be felt. Magnets are easy to make and their usefulness is quite common. Everyone knows that there is a gravitational field between matter. Similar to a magnetic field, it is a field that fills the space around a magnetic pole. The size of the magnetic field can be expressed by the number of imaginary magnetic lines of force. The denser the magnetic field lines, the stronger the magnetic field. On the contrary, the weaker the magnetic field lines are.

When a strong magnet is in motion, the charged particles will be subjected to a kind of Lorentz force in the magnetic field. The magnetic field strength of the charged particles is distinguished by the strength of the Loren magnet in different magnetic fields. Tesla is an international unit specifically used to measure magnetic flux density. The density of magnetic flux is the basic physical quantity describing its magnetic field, and the intensity of the magnetic field is an auxiliary quantity describing the magnetic field.

2. The strong magnet is called permanent magnet, so, does it really not demagnetize?

Strong magnets are known as permanent magnets. According to reason, demagnetization has nothing to do with time. There are two main factors that cause magnet demagnetization, temperature and oxidation. If the temperature is too high, it will lose magnetism if it exceeds the Curie temperature of 300 degrees Celsius. If the protection is not good, it will lose magnetism if it is oxidized, and this is the biggest reason for magnet failure during use. Powerful magnets have the characteristics of small size, light weight and strong magnetism, and are the magnets with the better performance-to-price ratio so far. As a third-generation rare earth permanent magnet material, magnets have a high cost-performance ratio. They are widely used in energy, transportation, machinery, medical, IT, home appliances and other industries, especially with the development of knowledge economy represented by information technology. It continuously brings new uses to the rare earth permanent magnet industry and other functional materials, which brings a broader market prospect for the NdFeB industry.

3. Analyze from how much energy the strong magnet can store

How much energy can be stored by a powerful magnet? How to make a sintered NdFeB permanent magnet is an iron-based permanent magnet made by powder metallurgy. The main processes include formula smelting, powder forming, orientation sintering, mechanical processing, electroplating, etc. Among them, the control of oxygen content is an important indicator to measure the level of the process. How much energy a magnet can store Even after a long time of use, the magnetic properties of the magnet are the magnetic field energy generated by the unit volume of data, and the amount of energy the magnet can store is a physical quantity. Commonly used magnetic measuring instruments Commonly used magnetic measuring instruments are fluxmeter Teslameter, also known as Gauss meter magnetometer. The flux meter is used to measure the magnetic induction flux. The magnetic meter is used to measure the comprehensive magnetic performance.
