source:PhysicsworldResearchers in Japan have built the first nuclear magnetic resonance (NMR) magnet that incorporates high-temperature superconductors with truly superconducting joints between them. This breakthrough all-superconducting configuration enables the device to operate at relatively high magnetic fields in so-called persistent mode, making it suitable for applications such as maglev trains and magnetic resonance imaging (MRI). The new device might also serve as a stepping-stone towards persistent-mode magnets that work at even higher magnetic fields, without the need for liquid hel...

source:Yahoo!finance EVs certainly mark the path to a more environmentally friendly future, but there are still concerns around the sourcing of certain components or materials within EVs. As the market for EVs expands rapidly, the demand for components like electric motors does so along with it. In 2021, the demand for EV motors is expected to increase by 40% in the car market alone. Electric motors literally drive EVs, but many designs utilize kilograms of magnetic materials. These magnets rely heavily on rare-earth materials like neodymium and dysprosium, which are expensive, produce lo...
