What are the magnetic properties of the Disc Magnet With Hole, and what types of materials can it adsorb?

The reason why the Disc Magnet With Hole has excellent high magnetic properties is that NdFeB, as the third-generation rare earth permanent magnet material, has extremely high magnetic energy product and remanence. The magnetic energy product refers to the magnetic energy density established by the magnet in the air gap space, that is, the static magnetic energy per unit volume of the air gap. The higher the magnetic energy product, the more magnetic energy the magnet can store in the same volume, thereby generating a stronger magnetic force. Remanence refers to the magnetic induction intensity retained by the magnet when the external magnetic field is removed after magnetization. The higher the remanence, the stronger the magnetism of the magnet.

Taking the common Disc Magnet With Hole as an example, these magnets make full use of the characteristics of high-quality materials in the design and manufacturing process, so that the single-piece magnet can adsorb more than 60 kilograms of pure iron. This powerful adsorption capacity makes the Disc Magnet With Hole widely used in many fields. In industrial production, it can be used to fix and transport iron parts to improve production efficiency; in the field of logistics and warehousing, it can quickly absorb and organize goods with ferromagnetic labels to achieve rapid classification and storage of goods.

The Disc Magnet With Hole has excellent anti-demagnetization performance, which is one of the important reasons for its excellent performance in practical applications. In some special working environments, such as high temperature environments or environments with complex magnetic fields, ordinary magnets can easily weaken or even disappear due to external factors, thus affecting their normal use. However, the Disc Magnet With Hole can maintain stable magnetism in such an environment.

In a high temperature environment, the magnetic domain structure inside the magnet is easily affected by thermal motion and changes, resulting in weakened magnetism. However, the high-quality magnetic material selected for the Disc Magnet With Hole has a high Curie temperature, which refers to the temperature at which the magnetism of the magnetic material completely disappears during the heating process. Due to its high Curie temperature, the magnetic domain structure inside the magnet can remain relatively stable within a certain temperature range, thereby ensuring the stability of the magnetism. In a complex magnetic field environment, the external magnetic field may interfere with the magnetization direction of the magnet, but the Disc Magnet With Hole can effectively resist this interference and maintain the stability of its own magnetism by virtue of its unique material properties and structural design.

If the temperature resistance of the magnet is not good, the problem of magnetism decline is likely to occur, thus affecting the normal operation of the equipment. The temperature resistance of the Disc Magnet With Hole can ensure that it still maintains stable magnetic properties in such a high temperature environment, and will not affect its adsorption effect and service life due to temperature changes. For example, in some high-temperature baking equipment, the Disc Magnet With Hole can be used to fix and position metal parts to ensure that the parts will not shift during the baking process, ensuring the quality and efficiency of production.

The Disc Magnet With Hole has a strong adsorption capacity for ferromagnetic metals such as iron, nickel, and cobalt and their alloys. The reason why ferromagnetic metals can be adsorbed by magnets is that there are a large number of magnetic domains inside them. The magnetic domain is a small area of ​​spontaneous magnetization inside the ferromagnetic material. When there is no external magnetic field, the magnetization direction of each magnetic domain is chaotic and does not show magnetism on a macro scale. But when the magnets are close, the magnetic field generated by the magnets will make the magnetization directions of these magnetic domains tend to be consistent, thus producing an obvious adsorption effect.
