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 [...]
Rare earth element (REE) Nd-Fe-B and Sm-Co permanent magnets Rare earth element (REE) established Nd-Fe-B and Sm-Co permanent magnets are widely used due to their excellent magnetic properties. An electric car like GM''s Chevrolet Volt utilizes seven pounds of rare-earth magnets, while every clean-energy wind turbine uses over 600 pounds of neodymium (Nd). China accounts [...]
