Superconducting magnet

Superconducting magnets refer to the general term for superconducting coils and its maintenance of low temperature containers. Superconducting magnets are the most important core components of the superconducting suspended railway. The promotion, suspension, and guidance of vehicles are generated by the superconducting coil. Like permanent magnets, superconducting magnets can provide stable magnetic fields, and superconducting magnets can also provide high -strength magnetic fields that general permanent magnets cannot provide. This is also the reason why the magnetic floating railway uses superconducting magnets. Due to the development of high -temperature superconductors, superconducting phenomena is generated under the temperature of liquid nitrogen (78K), which greatly improves the performance of superconducting materials. However, as a superconducting material used as a magnetic floating railway, the critical currents of high -temperature superconducting materials in high -strengt

Single -sided magnet

The magnetic refraction of the single -sided magnet is like the refraction of the signal or the refraction of the light on the signal of the satellite pot. The refractive effect is mainly determined by the following three aspects: 1. Materials: material selection and thickness, and the distance between the magnet and the material is closely close to Relationship. Pure iron skin is easy to leak magnetic. After special treatment, the refraction will be enhanced, but the 100%shielded materials have not yet been studied, but the effects of materials made by different manufacturers are also different. 2. angle: According to the principle of refraction, the arc material is the best effect, and the refractive loss of right -angle materials is large. 3. Space: The magnetic line is like a mobile phone signal in the air, which requires space to refract. If the firecracker cooker is completely wrapped on the lamp gun, the effect is not good, because a large amount of light refraction is lost. How

Aluminum, nickel cobalt and sagnic cobalt magnets

Aluminum nickel cobalt (Alnico) is the earliest permanent magnet material developed. It is a alloy composed of aluminum, nickel, cobalt, iron, and other trace metal elements. According to different production processes, it is divided into sintered aluminum nickel cobalt (Sinteered Alnico) and cast aluminum nickel cobalt (Cast Alnico). The shape of the product is mostly round and square. The casting process can be processed and produced into different sizes and shapes; compared with the casting process, sintering products are limited to small sizes, and the blank size tolerance is better than the blanking of the cast product. Machining is good. In the permanent magnet material, the cast aluminum nickel cobalt permanent magnet has a minimum reversible temperature coefficient, and the operating temperature can be as high as 600 ° C. Aluminum nickel cobalt permanent magnet products are widely used in various instrument and other applications. The） cobalt (SMCO) is divided into SMCO5 and SM

Rubber magnet

Rubber Magnet is one of the iron oxygen magnetic series. It is softened and squeezed out by bonding iron oxygen powder and synthetic rubber. Elasticity and twisted magnets. It can be processed into strips, curls, sheets, and various complex shapes. The rubber magnet is made of magnetic powder (Sro6fe2O3), polyethylene (CPE), and other additives (EBSO, DOP), and is manufactured by squeezing and pressure. The rubber magnetic material can be the same or heterogeneous. It is made of iron oxygen magnetic powder, CPE and certain trace elements, which can be bent, twisted, and can be rolled. It does not need more mechanical processing to use it. It can also be trimmed according to the required size. The rubber magnet can also be re -enabled PVC, gum, UV oil, etc. according to customer requirements. Its magnetic energy accumulates between 0.60 and 1.50 mgoe. Application of rubber magnetic materials: refrigerators, message notice racks, fixing objects in metal body for fasteners such as adverti

Permanent magnet classification

(1) Alloy permanent magnet materialIncluding rare earth permanent magnet materials (钕 iron boron ND2FE14B), lattice cobalt (SMCO), aluminum nickel cobalt (Alnico)(2) Ferrite material (Ferrite)Classified according to the production processAccording to different production processes, it is divided into: sintering iron oxygen, bonding iron oxygen, and injection of iron oxygen. These three processes are divided into equal and heterogeneous magnets based on the orientation of magnetic crystals. [1]The above is the main permanent magnet material on the market, and some are eliminated due to the production process or cost reasons. ), FE-Co-V (Iron Cobalt), MNBI (Manganese)

Rare earth permanent magnet material

Rare earth permanent magnet material ( iron boron ND2FE14B) is divided into the following three types according to different production processes:(1) Bonding （b （(Bonded NDFEB)Plug -in iron boron is a composite cymbal iron boron permanent magnet with a composite cymbal iron boron -boron permanent mixing with adhesives such as resin, plastic or low melting point metal, and then using compression, squeezing or injection molding. The product is formed first, and there is no need to make a secondary processing, which can be directly made into various complex shapes. Each direction of bonding the iron boron is magnetic, and it can be processed into iron boron compressed molds and injection molding molds. High precision, excellent magnetic properties, good corrosion resistance, and good temperature stability.(2) Sintened NDFEBThe sintering iron boron permanent magnet is smelted after being grinded by the airflow. The stubborn power is very high and has a high magnetic performance. Its maximu
