How to Identify the North and South Poles of Arc Magnets? Arc magnets, also known as curved magnets or tile magnets, are one of the most widely used magnet types in motors. Their unique curved design allows them to fit the rotor or stator more effectively, making them an essential component in various motor applications. [...]
Magnet Temperature Limits: Maximum Operating Temperature vs Curie Temperature Temperature is one of the key factors affecting the performance and reliability of permanent magnets. Beyond a certain temperature threshold, magnets may even undergo irreversible demagnetization. Therefore, understanding the temperature limitations of magnets is crucial when selecting suitable magnet materials for specific applications. When evaluating the [...]
Top 15 SmCo Magnets Manufacturers in the World If someone asks for the strongest possible permanent magnet, SmCo is rarely my first answer. If the same customer says the magnet will sit next to a hot motor winding, work downhole, or hold a stable field for years with very little drift, the conversation changes. That [...]
What Are the Differences Between Sm1Co5 and Sm2Co17 Magnets There are two options of magnet which are commonly used in high-temperature motors or the aerospace manufacturing: Sm1Co5 and Sm2Co17. Both of them are samarium-cobalt magnet (SmCo), which is a type of rare-earth magnet. The number in the name represented the atomic ratio between samarium (Sm) [...]
How Does Temperature Affect SmCo Magnets? Samarium cobalt (SmCo) magnets are a type of rare earth magnet known for their exceptional magnetic strength, high resistance to demagnetization, and stability across a wide range of temperatures. Unlike neodymium magnets, which tend to lose strength at higher temperatures, samarium cobalt magnets retain their magnetic properties remarkably well, [...]
Loss of Permanent Magnet Magnetization Due to Cold Temperatures Exposure Loss of magnetization due to cold temperatures exposure is a phenomenon that occurs in various types of materials, particularly in magnetic materials. This phenomenon is commonly known as the “superparamagnetic effect” or “temperature-dependent magnetization.” It results from the thermal agitation of the atomic spins in [...]
Loss of Permanent Magnet Magnetization Caused by Heat Exposure Loss of Magnetization Caused by Heat Exposure - Exposing a magnet to high temperatures can decrease its strength or permanently damage its structure. Usually this happens at very high temperatures, but for certain neodymium magnets this can happen as low as 60°C. Magnets are characterized by [...]
Customised Magnets for The Automotive Industry Automotive challenges The automotive industry operates according to the Just-In-Time (JIT) principle. One of the prerequisites for successful JIT production is a reliable supply chain of suppliers that meet the defined quality requirements. It is important that they can respond to changes in prices, specifications and forecasts. This keeps [...]

Samarium Cobalt Magnets are among the second most common rare earth magnets. They can be used in temperatures on both the hottest and coldest end of the spectrum (although some swings [...]
High Temperature Resistant Permanent Magnets List Do you know which magnets have high temperature resistance? What are the magnets that can work at high temperature? What is the maximum temperature they can withstand? If you are looking to find the answers to the above questions, you are in the right place, in this article, we [...]
Types of Magnets Magnets are common in normal life, and almost everyone knows about them. In particular, magnets are known as those materials that have the property of attracting and repelling certain metal materials, such as iron and nickel. However, this is not always the case. Magnets can sometimes lose their magnetic property and thus [...]
