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, [...]
Magnet Glossary A Air Gap An air gap is non-magnetic material present between a magnet and an attracted object or between two magnets attracting each other. It acts as a break in the magnetic circuit, weakening the magnetic hold. The air gap can be filled with air, wood, plastic, aluminum, paint, or any uneven surface. [...]
Neodymium Magnet Glossary Welcome to our comprehensive glossary of neodymium magnets. As a leading supplier of high-quality magnets, we understand the importance of having a solid grasp of magnet terminology. Whether you're an industry professional, a hobbyist, or simply curious about the fascinating world of magnets, our glossary is designed to provide you with clear [...]
Determining Factors that Affect Magnetic Field Strength Consider a magnet's characteristics. Magnetic properties are described using these characteristics: Coercive magnetic field strength, abbreviated Hc. This represents the point at which the magnet can be demagnetized (degaussed) by another magnetic field. The higher this number, the more difficult it is to degauss the magnet. Residual magnetic [...]
What are the Properties of a Neodymium Magnet? The main characteristic of neodymium magnets is how strong they are for their size. The magnetic field of a neodymium magnet occurs when a magnetic field is applied to it and the atomic dipoles align, which is the magnetic hysteresis loop. When the magnetic field is removed, [...]
How Does Temperature Affect Different Magnets? The relationship between magnetic strength and ambient temperature is somewhat complicated. If you are in need of a magnet, however, it is important for you to understand how temperatures affect the strength of different types of magnets before choosing a product. This will allow you to choose the magnet [...]
Working With Magnets in High or Low Temperatures The ambient temperature surrounding your magnets during work impact their strength significantly, but each magnetic material is different. Which magnet works best in your conditions? Temperature and magnetic strength have a turbulent relationship. Some applications require magnets in freezing conditions, while others work in searing heat. Some [...]
How Are Alnico Magnets Made? Alnico magnet was successfully developed in the 1930s. It is composed of aluminum, nickel, cobalt, iron, and other trace metal elements. Thanks to their high coercivity and high Curie temperature, Alnico magnets are widely used in many industrial and consumer products, such as motors, electric guitar pickups, microphones, sensors, speakers, [...]
Use Rare Earth Magnets Outdoors Lanthanide components are ferromagnetic metals. This implies that they the ability to be charged much the same as iron. Be that as it may, their curie temperatures (the temperature at which they lose their attraction) are normally underneath the typical room temperature. This illustrates why rare magnets are not suitable [...]
Permanent Magnets Operating Temperatures All Permanent Magnets experience variations in field strength (flux density) as the ambient temperature increases or decreases. How these variations in operating temperature influence magnetic strength depend on the type of magnetic material and the degree above or below ambient temperature in which they are expected to operate. The shape of [...]
