Introduction to the principle of magnet power generation, Free electrons in a conductor are subject to the Lorentz force According to the law of conservation of energy, energy cannot be generated without reason, nor can it disappear without reason. The electric energy generated by magnets must come from other forms of energy. Physics tells us: [...]
Superconducting Magnets: Power Unplugged Superconductivity is a very cool phenomenon in which electrical resistance is overcome with the help of very cold temperatures colder than anything this side of Pluto! Most superconducting magnets are made using an alloy called niobium-titanium "Ni-Ti" for short. You could think of it this way: In a superconducting current, the [...]
A Boost for Permanent Magnets Scientists at TU Darmstadt explored on an atomic level how changes in iron content influence the micro-structure of samarium-cobalt based permanent magnets. Their results were published in Nature Communications. In the long run they could contribute to the development of permanent magnets with improved magnetic performance. These magnets can be [...]
Scientists Discover Potential Path to Improving Samarium-Cobalt Magnets Scientists have discovered a potential tool to enhance magnetization and magnetic anisotropy, making it possible to improve the performance of samarium-cobalt magnets. The scientists, at the U.S. Department of Energy's Critical Materials Institute at Ames Laboratory, in collaboration with the Nebraska Center for Materials and Nanoscience and [...]
What are Temperature Coefficients of Permanent Magnets? A new approach for calculating the temperature coefficients of magnetic parameters is proposed in order to more accurately describe high temperature characteristics of magnetic materials. Using this new approach, the "true" (or instantaneous) temperature coefficient of any magnetic parameter at a specific temperature can be determined and a [...]
Multi-pole Magnetic Rotor Assembly for USA Electric-motor Customer HSMAG has secured an order for the supply of 600 multi-pole Samarium Cobalt (SmCo) magnetic rotor assemblies annually to a USA prominent Electric-motor customer. The magnetic rotor order was placed at the end of 2018 with deliveries starting in 2019 and running for 10 years. The HSMAG [...]
HSMAG Supply Magnet Ensure Quality and Delivery on Time in COVID19 After the COVID19 pandemic, domestic market is increasing sharply. Customers put forward higher requirement on us to shorten delivery time to make up for the time delayed due to the coronavirus situation. HSMAG Supply Magnet Ensure Quality and Delivery on Time in COVID19 [...]
Samarium Cobalt MATERIAL GRADES Known as Rare Earth magnets, Samarium Cobalt (SmCo) are alloys of the Lanthanide group of elements. SmCo magnets have been commercially available since the early 1970’s, first as a 1-5 Type alloy, and later with the introduction of the 2-17 type. Both alloys offer outstanding thermal stability and excellent corrosion resistance. [...]
Design and Recycling of Rare-Earth Permanent Magnet Motors and Generators in Hybrid and Full Electric Vehicles DEMETER – European Training Network for the Design and Recycling of Rare-Earth Permanent Magnet Motors and Generators in Hybrid and Full Electric Vehicles In 2010 the European Commission (EC) published a milestone report on Critical Raw Materials (CRM) for [...]
Sintered SmCo General Information Collectively known as Rare Earth magnets, Samarium Cobalt (SmCo) and Neodymium Iron Boron (NdFeB) magnets are alloys of the Lanthanide group of elements. Rare Earth magnets are the most advanced commercialized permanent magnet materials today. SmCo magnets are available in a number of different grades that span a wide range of [...]
SmCo Rare Earth Magnets Overview Samarium Cobalt Rare Earth magnets (also known as SmCo magnets) are another type of permanent magnet. A big advantage of SmCo magnets is that they can operate at temperatures up to 300 degrees Centigrade. SmCo magnets are widely used in applications in which high operating temperature and high corrosion and [...]

Why are Samarium Cobalt and Neodymium Magnets Called Rare Earth Magnets? There are seventeen rare earth elements– fifteen of which are lanthanides and two of which are transition metals, yttrium and scandium, that are found with lanthanides and are chemically similar. Samarium (Sm) and Neodymium (Nd) are the two most commonly used rare earth elements [...]
Magnet Machining Process Magnet Machining Process - Magnets that have been through the sintering process are machined and plated. Machining Due to shrinkage from the sintering process, required measurements are achieved by grinding the magnets with abrasives. Diamond abrasives are used for this process because the magnet is very hard. machining Surface Treatment (Plating) [...]
Neodymium vs. SmCo Magnets used for Hybrid Electric Vehicles Permanent Magnets Dominate EV Neodymium vs. SmCo Magnets - Vehicle electrification is a growing market for rare earth magnets. Consumption of rare earth magnets in transportation is estimated to rise from 7,000 tons in 2015 to 17,000 tons in 2020. Government mandates to reduce pollution, as [...]
