Must-know industry jargon in the permanent magnet field — today’s topic 👇 🔴 Surface Magnetic Field (Gauss) Refers to the magnetic flux density measured at a specific point on the surface of a magnet. The value varies across different positions (center vs. edge), and is typically measured using a Gauss meter in contact with the magnet surface. It’s important to note that this value does not represent the overall magnetic performance of the magnet. 🔴 Magnetic Flux Defined as the product of magnetic flux density (B) and the area (S) perpendicular to the magnetic field. It represents the total number of magnetic field lines passing through a given surface, with the unit Weber (Wb). In simple terms, it reflects how much “magnetic field” a magnet can emit or absorb — higher flux means stronger magnetic output capability. 🔴 Magnetic Orientation Magnetic materials are divided into isotropic and anisotropic types. Isotropic magnets: same magnetic properties in all directions, can be magnetized freely. Anisotropic magnets: magnetic properties vary by direction, and they have a preferred direction where the best magnetic performance is achieved — this is called the orientation direction. 💡 These concepts are key to understanding magnet design, measurement, and real-world applications. 📌Okay, what other slang terms from the permanent magnet industry do you know?

March 20th prices from Asia Metal: PrNd metal: 885–890 RMB/kg Nd metal: 975–980 RMB/kg DyFe alloy: 1,360–1,380 RMB/kg Tb metal: 7,750–7,850 RMB/kg PrNd prices fell sharply this week. Compliant production capacity has been gradually coming online, and factory production has stabilized after Chinese New Year. Bound by futures contracts and long-term agreements, downstream magnetic material manufacturers have made only sporadic purchases. Traders are strongly bearish, selling at higher prices and buying at lower levels. Prices continue to test support levels. Influenced by sluggish inquiries and actual purchases from magnetic material manufacturers, the price of DyFe has continued to decline, while the price of Tb has undergone minor adjustments.

Must-know industry jargon in the permanent magnet field — today’s topic 👇 🔴 Maximum Energy Product (BH)max Represents the maximum magnetic energy density a magnet can deliver in the space between its poles. It is the maximum value of the product of B and H, and directly indicates the overall performance level of a magnet — the higher the value, the stronger and more efficient the magnet. 🔴 Curie Temperature The theoretical upper temperature limit at which a magnetic material can retain its magnetism. For NdFeB magnets, it is typically around 320–380°C. This value is closely related to the material’s crystal structure formed during sintering. Once the temperature reaches the Curie point, intense molecular motion causes irreversible demagnetization. Although the magnet can be re-magnetized, its magnetic strength will significantly drop—usually to about 50% of the original level. 🔴 Working Temperature Refers to the maximum temperature at which a magnet can operate continuously while maintaining stable performance within an acceptable loss range. For sintered NdFeB magnets, the working temperature is much lower than the Curie temperature. Within this range, magnetic strength may decrease as temperature rises, but most of it will recover after cooling. 💡 Understanding these parameters helps you choose the right magnet for high-performance and high-temperature applications! 📌 Follow us for more insights into the permanent magnet industry Click to learn more: https://lnkd.in/ggamNbnE Email: sales02.jlmaginnovation@jlmag.com.cn #PermanentMagnets #NdFeB #MagneticMaterials #EngineeringBasics #IndustrialKnowledge #MagnetDesign #Manufacturing #B2B #TechInsights

Must-know industry jargon in the permanent magnet field — today’s topic 👇 🔴 Coercivity (Hcb) Refers to the reverse magnetic field strength required to reduce the magnetic induction to zero during demagnetization. At this point, the magnetization of the material is not actually zero—it is offset by the applied reverse magnetic field. Even after removing the external field, the magnet still retains some magnetism, which is the magnetic force we observe externally. 🔴 Intrinsic Coercivity (Hcj) The reverse magnetic field strength required to reduce the magnet’s magnetization to zero. It reflects the material’s inherent resistance to demagnetization. In the industry, magnet grades (such as N, M, H, UH, EH) are classified based on the level of intrinsic coercivity. 🔴 Remanence (Br) The magnetic induction remaining in a magnet after it has been fully magnetized and the external magnetic field is removed. Simply put, it represents how much magnetism is retained after magnetization. The unit is typically Tesla (T) or Gauss (Gs), where 1 Gs = 0.0001 T. 💡 Master these three parameters, and you can understand 80% of magnet performance data sheets! 📌 Follow us for more insights into the permanent magnet industry Click to learn more: https://lnkd.in/ggamNbnE Email: sales02.jlmaginnovation@jlmag.com.cn #PermanentMagnets #NdFeB #MagneticMaterials #EngineeringKnowledge #Manufacturing #IndustrialInsights #MagnetTechnology #B2B #TechExplained

Still confused by basic concepts like "magnetism" and "magnetic materials"? Understanding them is key to truly grasping the underlying logic of permanent magnet materials! 💡 Magnetism:  Experiments show that any substance can be magnetized to some extent in an external magnetic field, only the degree of magnetization differs. Based on the properties exhibited by substances in an external magnetic field, substances can be divided into five categories: paramagnetic substances, diamagnetic substances, ferromagnetic substances, ferrimagnetic substances, and antiferromagnetic substances. We call paramagnetic and diamagnetic substances weakly magnetic substances, and ferromagnetic and ferrimagnetic substances strongly magnetic substances. Magnetic Materials: Soft Magnetic Materials: These materials can achieve maximum magnetization with minimal external magnetic field strength. They are magnetic materials with low coercivity and high permeability. Soft magnetic materials are easily magnetized and easily demagnetized. Examples include soft magnetic ferrites and amorphous nanocrystalline alloys. Hard Magnetic Materials: Also called permanent magnet materials, these are materials that are difficult to magnetize and difficult to demagnetize once magnetized. Their main characteristic is high coercivity. Examples include rare-earth permanent magnet materials, metallic permanent magnet materials, and permanent magnet ferrites. Functional magnetic materials mainly include magnetostrictive materials, magnetic recording materials, magnetoresistive materials, magnetic bubble materials, magneto-optical materials, and magnetic thin film materials.
