Epoxy coated shaped magnet The reason why neodymium iron boron undergoes demagnetization in high-temperature environments is determined by its physical structure. The reason why a general magnet can generate a magnetic field is because the electrons carried by the material itself rotate around the atoms in a certain direction, generating a certain magnetic field force, which in turn affects related affairs around it. However, there are certain temperature restrictions on the rotation of electrons around atoms in a given direction, and different magnetic materials can withstand different temperatures. In cases of excessive high temperature, electrons will deviate from their original orbits, causing chaos. At this time, the local magnetic field of the magnetic material will be disrupted, leading to demagnetization.Generally speaking, the demagnetization temperature of neodymium iron boron depends on its specific composition, magnetic field strength, and heat treatment history. Normally, the demagnetization tempera: 07

Several effective solutions for high-temperature demagnetization of neodymium iron boron magnets 1、 Do not place neodymium iron boron magnet products at excessively high temperatures, especially pay attention to their critical temperature. The critical temperature of ordinary neodymium iron boron magnets is usually around 80 degrees Celsius (176 degrees Fahrenheit). Adjusting the working environment temperature in a timely manner can minimize demagnetization phenomena.2、 Starting from technology, we aim to improve the performance of products using neodymium iron boron magnets, enabling them to have a more temperature sensitive structure and less susceptible to environmental influences.3、 You can also choose high coercivity materials with the same magnetic energy product. If that's not enough, you can only sacrifice a little magnetic energy product and find materials with higher coercivity that have a lower magnetic energy product. If that's not enough, you can choose to use samarium cobalt. As for reversible demagnetization, you can only choose samarium cobalt.PS: Each mat: 07

Surfboard motor magnet A surfboard motor usually refers to an electric power assist system installed on a surfboard to help surfers navigate the waves. This motor system typically includes components such as an electric motor, battery, controller, etc. Today, this article mainly discusses the role of magnets, materials, magnetic field strength, shape, etc.The role of magnets in electric surfboard motors;The main function of a magnet in a surfboard motor is to interact with the motor to generate driving force. The motor usually uses current to pass through the coil to generate a magnetic field, while the magnet can generate force that interacts with the motor's magnetic field. By adjusting parameters such as current and magnetic field strength, the interaction between the magnet and the electric motor can be controlled, thereby adjusting the driving force of the surfboard and helping surfers travel on the waves.The magnet material of the surfboard motor;Magnets can be divided into two common types: perman: 06

A Brief Discussion on the Characteristics of Permanent Magnet Ferrite Manufacturers In 1930, a permanent magnet with a spinel (MgA12O4) structure was discovered. Due to its brittle nature, complex process, low magnetic properties, and cobalt content, this type of magnet was not widely used at that time. After 20 years of continuous development, a high resistance non-metallic magnetic material - ferrite - was born on the basis of spinel. This brought revolutionary changes to the radio industry, pulse, and microwave technology at that time. In the 1970s, due to the easy oxidation, low Curie temperature, and high cost of metal permanent magnet materials, ferrite had the opportunity to develop. At present, ferrite has become the highest production permanent magnet ferrite material.Magnetic materials are the fundamental functional materials in the electronics industry. Permanent magnet materials, as an important component of magnetic materials, play an important role in industries such as electronics, information technology, motorcycles, electric tools, and automobiles.
