The Power of Neodymium Magnets

The Power of Neodymium Magnets Neodymium magnets, also known as NdFeB, NIB, or Neo magnets, are a type of rare-earth magnet. They are made from an alloy of neodymium, iron, and boron to form the Nd2Fe14B tetragonal crystalline structure. This material is currently the strongest known type of permanent magnet.To get more news about Neodymium Magnet, you can visit our official website.

The discovery of neodymium magnets dates back to 1982 when General Motors and Sumitomo Special Metals discovered the Nd2Fe14B compound. The magnets have found wide use in numerous applications due to their exceptional magnetic properties.

Neodymium magnets have a very high energy product, which measures the magnetic energy that can be stored in a magnet. This makes them extremely useful in a variety of applications. For instance, they are used in computer hard drives to read data. They are also used in medical devices, such as magnetic resonance imaging (MRI) machines.

Despite their strength, neodymium magnets are quite brittle and can be easily damaged if not handled with care. They are also prone to corrosion, which can be prevented by adding a protective coating.

One of the major challenges in the use of neodymium magnets is their reliance on rare earth elements. These elements are not evenly distributed around the world, leading to geopolitical tensions. Moreover, the extraction process of these elements poses environmental concerns.

In conclusion, neodymium magnets, with their exceptional magnetic properties, have revolutionized many industries. However, their future use depends on overcoming the challenges associated with their production and handling.

How Neodymium Magnets Are Made

Ferromagnetic substances such as iron, cobalt, nickel or ferrite are different. The electron spins in them can be arranged spontaneously in a small range to form a spontaneous magnetization region, which is called a magnetic domain.

Ferromagnetic materials after magnetization, the internal magnetic domains neatly arranged in the same direction, so that the magnetism is strengthened, constituting a magnet. The magnet's absorption process is the magnetization process of the iron block. The magnetized iron block and the magnet produce attraction between different polarities, and the iron block is firmly attached to the magnet.

Natural magnets are Fe3O4, whereas artificial magnets are usually steel. Steel after magnetization will always retain magnetism generally referred to as the natural permanent magnet iron is not only ferrite, but also iron cobalt nickel alloy, iron-rare earth alloy and other permanent magnet materials, such as aluminum nickel cobalt, samarium cobalt, neodymium iron boron, these are also common, magnetic is very strong, these materials can be magnetized by magnetic field, and magnetization It is magnetic and does not disappear. The composition of artificial magnets depends on the magnetization properties of various metals. A magnet is close to a magnetic substance, which is induced at one end to form an anonymous pole and at the other end to form an anonymous pole.

Classification of magnets:

A. temporary (soft) magnet

Meaning: magnetism is transient, and magnetism disappears when the magnet moves away. Case: iron nails and wrought iron

B. permanent (hard) magnet

Meaning: magnetization can keep magnetism for a long time. Case: steel nails

According to the principle of electromagnetic induction, a strong current can produce a strong magnetic field, using a strong magnetic field to magnetize ferromagnetic materials, and because different materials have different magnetization characteristics, some materials are easy to magnetize, and not easy to drop magnetism (loss of magnetism), can retain magnetism for a long time. The magnetization of this substance produces a magnet.

According to the principle of electromagnetic induction, electric currents can produce magnetic fields. Magnetizing hard magnetic materials by means of strong magnetic fields are generally called magnets. In fact, there are several different things: the most common magnets, such as magnets for general loudspeakers, are ferrite magnets. They are made of iron scales (flaky iron oxides) which fall off the surface of billets during hot rolling in iron and steel plants. After removing impurities, crushing and adding a small number of other substances, they are pressed into steel molds and then sintered in a reducing electric furnace (through hydrogen), so that some oxides are reduced to ferrite, cooled, and then cooled. Magnetizing is produced in the exciter.

More advanced than they are magnets: magnets are real steels, made up mainly of nickel with a higher content than iron. It is generally melted by the medium-frequency furnace, casting molding, because some of the plane precision requirements, generally need to use the grinding machine. Then magnetized and become a product. This kind of magnetic steel is used in various meters. The more advanced magnetic materials are neodymium iron boron magnetic materials. They are neodymium, iron and boron-containing rare earth elements. It is made of cemented carbide by powder-mixing-molding-sintering-finishing-magnetizing.

This kind of magnetic material has the highest magnetic field intensity, the best performance, and the most expensive price. It will be used in the national defense industry and precision equipment. The rotor of the stepping motor in the electronic table is. Ah, the magnetic suspension train is definitely used for this magnetic material. Ferrite permanent magnet materials include strontium-ferrite permanent magnet materials and barium-ferrite permanent magnet materials. There are isotropy and anisotropy in them. Ferrite magnet materials are widely used in loudspeaker magnets. Aluminum-nickel-cobalt permanent magnet materials and rare earth permanent magnet materials are the main permanent magnet materials. Rare earth permanent magnet materials include samarium cobalt permanent magnet material and NdFeB permanent magnet material. Rare earth permanent magnet materials are made by powder metallurgy process.

There are too many classifications of magnets. There are two main types of magnetic materials: the first is permanent magnetic materials (also known as hard magnetic): the material itself has the characteristics of magnetic force preservation. The second is the soft magnet (also known as the electromagnet): the need for external electricity to produce the magnetic force, we usually say that the magnet, generally refers to permanent magnet materials.

There are also two categories of permanent magnet materials: the first category is: alloy permanent magnet materials include Nd2Fe14B, SmCo, NdNiCO. The second category is: Ferrite is divided into Sintered Ferrite, Rubber Magnet, and Plastic Ferrite according to the different production process, and these three processes are divided into isotropic and heterogeneous magnets according to the orientation of magnetic crystals.

[torley]

General Motors (GM) and Sumitomo Special Metals independently discovered the Nd2Fe14B compound almost simultaneously in 1984.[3] The research was initially driven by the high raw materials cost of SmCo permanent magnets, which had been developed earlier. GM focused on the development of melt-spun nanocrystalline Nd2Fe14B magnets, while Sumitomo developed full-density sintered Nd2Fe14B magnets.[9] Consumer Culture https://en.wikipedia.org/wiki/Neodymium_magnet

The Neodymium-Iron-Boron Ternary System

Phase Poll #10 wrapped up yesterday with the final result as 42.5% Fe, 30% Nd, and 27.5% B. This ternary system is most well known for neodymium-iron-boron magnets, so we’re going to spend a little bit of time discussing those before we narrow in on the chosen composition.

Nd-Fe-B magnets are permanent magnets with the composition of Nd2Fe14B, considered to be an intermetallic, and a tetragonal crystal structure. (Permanent magnets are those materials which are magnetized and create their own magnetic field, such as refrigerator magnets.) These neodymium magnets are the most widely used rare earth magnets and have numerous applications, including in computers, speakers, door locks, electric generators, among countless others. These magnets are typically produced either through powder metallurgy and sintering, or through melt spinning.

The chosen composition results in another stoichiometric, intermetallic phase, NdB4. Its space group is P4/bmb, meaning it crystalizes with a tetragonal crystal structure as well. On their own, there is little interest in neodymium boron compounds in the literature.

The thermal expansion of rare earth permanent magnets and the 20mm diameter neodymium iron boron strong magnetic tension and Gauss value data reference

The thermal expansion and magnetostriction of rare earth permanent magnets will cause the size of the magnet to change to different degrees. If the thermal expansion and contraction of other assembly materials in the magnetic assembly are quite different, this size change will cause a certain stress to the magnet. It may cause mechanical damage or deterioration of the magnet. In the application of large-scale permanent magnet materials, thermal expansion and magnetostriction phenomena need to be given full attention.

Conventional metal and non-metal materials have positive linear expansion coefficients, so there are often sayings of thermal expansion and contraction. For example, the linear expansion coefficients of steel, copper and aluminum are 12 x 10-6/℃, 17 x -6/℃ and 24 x -6/℃. The coefficient of linear expansion of sintered ferrite and sintered samarium-cobalt magnet is within the range of (10~15) x 10-6/℃, which is very close to steel. Therefore, when these two magnets are assembled with iron yoke to produce magnetic components, No need to worry about mismatch caused by thermal expansion. However, the strong magnetocrystalline anisotropy of SmCo and ferrite will cause the thermal expansion coefficient of the sintered magnet that needs to be oriented to also have anisotropy, which is a phenomenon that needs to be considered in the preparation and application of the magnet.

The thermal expansion and contraction behavior of neodymium iron boron magnets is even more strange. At lower than the Curie temperature, the main phase Nd2Fe14B has obvious Invar effect, and the linear expansion coefficient perpendicular to its c-axis is negative, parallel to The linear expansion coefficient in the c-axis direction returns to a positive value after about 70°C lower than the Curie temperature, and the average value of the linear expansion coefficient is 1 x 10-6/°C.

The abnormal thermal expansion of neodymium iron boron magnets stems from the 3d electronic magnetic characteristics of iron atoms. For example, if the magnet is assembled with other materials into magnetic components by bonding, the mismatch during assembly and use is more serious.

20mm diameter neodymium iron boron strong magnetic tension and Gauss value data reference
