Speaker magnets are a crucial component in most speakers speaker magnet responsible for creating the magnetic field necessary for the speaker to function. Typically, they’re made of materials like ferrite (ceramic), neodymium, or even samarium-cobalt. These magnets interact with the electric current flowing through the voice coil, which in turn causes the speaker cone to move and produce sound waves. Neodymium magnets, in particular, are popular due to their strong magnetic properties, allowing for smaller and more powerful speaker designs. The speaker magnet is composed of several key components: T iron, magnet, voice coil and diaphragm. When an alternating current passes through the coil of the speaker (i.e., the […]

The permanent magnet in Apple’s magnetic wireless charger
Small neodymium magnet for wireless magnets Since the iPhone 8 in 2017, Apple has added wireless charging functions to all iPhone models. It is similar to the wireless charging method of other mobile phones. Charging starts when it is placed on the wireless charger. This wireless charging relies on the transmitting coil and The alignment of the receiving coil cannot achieve the best effect of placing it casually. If it is placed crookedly, it will cause problems such as reduced wireless charging efficiency, inability to increase power, slow charging, severe heating, etc., hindering the development of wireless charging and also causing disadvantages. experience. Starting from its roots small neodymium magnet, […]

表面磁性は計算できるのか？表面磁性と磁石の性能の関係
2024 neodymium magnet n52 Let’s take you through the relationship between surface magnetism and magnet performance. The concept and measurement of surface magnetism Surface magnetism, also known as surface field and surface magnetic field, refers to the magnetic induction intensity at a certain point on the surface of the magnet. The unit is Gauss Gs or Tesla T (1T=10000Gs). Surface magnetism is the most easily directly measured parameter in daily life. When the size of the magnet is certain, people often judge and compare the performance of the magnet by comparing the surface magnetism neodymium magnet n52. For some magnets that are particularly large or small in size and have […]
SmFeNサマリウム鉄窒素希土類永久磁石材料
Permanent Magnet Ndfeb NdFeB, as the third generation rare earth permanent magnet material, has been widely used due to its excellent magnetic properties. However, permanent magnet ndfeb magnets also have shortcomings such as low Curie temperature, large coercive force temperature coefficient, and poor chemical stability. The huge consumption of praseodymium, neodymium, dysprosium, and terbium rare earth resources has caused people to worry about environmental damage and the security of rare earth resources. Ongoing concerns. Therefore, while magnetic materials practitioners are constantly improving the performance of NdFeB permanent magnet materials, they are also actively developing other new permanent magnet materials. In 1990, Professor Coey from Ireland used gas-solid phase reaction to […]
