ferrite magnets

We all know that inside the speaker horn will use magnets, some partners will remove the magnet as a child, you can find the magnet inside is black, this is a ferrite magnet, that is, universal magnet. But with the development of the market, more and more speaker equipment inside the neodymium magnet will be used to replace the traditional speaker magnet. There are three types of magnetic materials in speaker magnets: alnico magnets, ferrite magnets, and neodymium-iron-boron magnets. Each type of material has a different effect on the tonal characteristics of a loudspeaker. 1. Alnico magnets are the initial magnet material used in loudspeakers to produce classic tones. These speakers sound warmer and sweeter at lower volumes, and many musicians find them more responsive to a player's touch. The disadvantages are low power, narrow frequency range, hard and brittle, and very awkward to work with. In addition, cobalt is a scarce resource and Alnico is relatively expensive. From the comprehensive cost-effective, speaker magnets using Alnico is relatively small. 2. Ferrite magnets are developed as a cheap alternative to Alnico. Ferrite magnets are generally made into external magnetic horn. The ferrite material has very low magnetic force and has to have a certain volume size to achieve the driving force of the horn. Therefore, it is usually used in louder audio speakers. The advantage of ferrite is that it is cheap and cost-effective; the disadvantages are large size, low power and narrow frequency range. 3. The last material is neodymium iron boron magnet So what are the advantages and disadvantages of neodymium iron boron speaker magnets? Advantages: high magnetic performance, small size, the weight will be lighter than other speakers, wide frequency range. Excellent sound quality, good elasticity, good detail, good voice quality and accurate sound field positioning. In terms of price, they are between Alnico and Ferrite magnet speakers. Mostly used in high end speakers. Disadvantages: disadvantages are sintered moulding, expensive, magnetic, easy to oxidise, slightly less bass, and high temperatures can cause irreversible magnetic degradation

Cat's eye magnets, also nail art magnets. It is used as an aid for women's nail art. Cat's eye nail glue contains magnet powder, which is adsorbed and gathered under the action of cat's eye magnet. Under the reflection of light, there is a band of light like the pupil of a cat's eye, i.e., there is a thin, narrow and bright reflection on the surface, and the effect is like a cat's eye stone. What are nail art cat eye magnets made of? Most of the cat eye magnets are neodymium iron boron magnets, also known as powerful magnets. NdFeB powerful magnets are the most magnetic type of permanent magnet material. Because of the super strong magnetic properties, they can be obtained during use in order to get clean, tight lines. Can I replace the cat's eye magnets with ordinary magnets? Ordinary magnets, also known as black ferrite magnets, are weak in magnetism and low in cost, if you use ordinary magnets for cat eye nail art, the shape presented may be irregular and the effect is not as good as strong magnets. So it is recommended to use a strong magnet. What are the specifications of nail art cat eye magnets? The common shapes of cat eye magnets are cylindrical, rectangular, round Disc magnet, spherical magnet several kinds. Such as cylindrical magnet size: D6*15/20/25/30MM, D8*6*15/20/25/30MM and so on. How much is the customised nail art cat eye magnets? The cost of customised cat eye magnets is different for different sizes, because NdFeB powerful magnets have different magnetic grades, so you must need to send samples to the supplier during the batch customisation process, according to the actual performance of the samples. In summary, cat eye magnets use NdFeB powerful magnets.

About ceramic magnet, many people do not know it belongs to which kind of magnet? Today, this article will introduce to you the material type, shape, application and its performance parameters of ceramic magnets. Ceramic magnets, also known as hard ferrite magnets, are composed of barium or strontium and were developed in the early 1960s as an alternative to more expensive metal magnets. These magnets are very hard, brittle, and have low energy properties compared to other magnetic materials. However, ceramic ferrite magnets are widely used due to their excellent demagnetization and corrosion resistance properties and superior price advantage. Ferrite magnets are manufactured by sintering or injection molding. These magnets can be anisotropic and isotropic. Anisotropic grades are oriented in the direction of manufacture and must be magnetized in that direction. Isotropic grades are not oriented and can be magnetized in any direction. Ceramic magnets can maintain 45% of their room temperature magnetic specification at 350 degrees Fahrenheit. The degradation is nearly linear as the temperature increases and the change in magnetization is essentially reversible until about 840°F, at which temperature the ceramic magnet is completely demagnetized. Ceramic magnets exposed to temperatures up to 1800 degrees Fahrenheit can be remagnetized for continued use. However, above 1800 degrees Fahrenheit, the changes are irreversible. Ceramic ferrite magnets are commonly used in shapes such as arc (tile), rectangle, square, torus, and cylinder. Applications for ceramic magnets include: loudspeakers, DC brushless motors, magnetic resonance imaging, magnetic separation for magnetic assemblies designed for lifting, holding and recycling.

The type of magnet material There are many types of magnet materials, common permanent magnets, ferrite magnets, neodymium magnets, Alnico magnets and so on. Different materials have different advantages and disadvantages, users should consider the use of the environment and needs when choosing magnets. Why there will be the case of broken magnets The reason why magnets are easy to crack, mainly because of the following reasons: 1. Quality issues: the manufacturing process of the magnet and the quality of the material directly determines whether the magnet is fragile. 2. Inappropriate use of the environment: such as high-temperature environment, humid environment, external forces, etc., will lead to fragile magnets. 3. Improper use: for example, forcing the magnet apart, using the wrong way to adsorb items, etc., will also lead to magnet damage or fragmentation. Which material of magnet is not fragile Generally speaking, magnets made of neodymium-iron-boron (NdFeB) are stronger and more durable than those made of other materials. NdFeB magnets are a kind of rare-earth magnets with very strong magnetic force and high wear resistance. Due to the continuous improvement of the production process and material quality of NdFeB magnets, nowadays NdFeB magnets are not easy to break. In addition, the magnetic force of NdFeB magnets is so strong that they can be used to make various kinds of iron absorbers, motors, computer hard disks and other high-tech devices.

As a general rule, neodymium magnets are lighter and more expensive, while ferrite magnets are cheaper, but they are heavier. You cannot say one magnet type is better than another regarding sound quality, as it depends on your speaker application. Promotional materials from speaker manufacturers are great at explaining why Neodymium magnets produce such good sound, yet many audiophiles enthusiastically talk about –and continue to love- the sound output of speaker systems made with ferrite magnets. So which magnet is the better speaker magnet? The reason so many have debated this is that the decision depends on a number of factors. Is the speaker designed for home? Will it be installed in an automobile? Is the voice coil optimized for the magnet? How well are the other components matched? Are size and weight important factors? The most appropriate magnet material is evident in speakers such as guitar speakers. I find that ferrite magnets have a lower “gnarl” sound, which can sound great for distortion and metal music; however, neodymium magnets have a brighter mid-range. Ultimately, the choice between neodymium and ferrite magnets for speakers boils down to a balance of factors, including cost, weight, size, and the specific sound qualities you aim to achieve. It’s always a good idea to experiment with both types to find the one that suits your individual sound preferences and setup.
