Developed independently in 1984 by General Motors and in the 1970s by Sumitomo Special Metals, [3] [4] [5] neodymium magnets are the strongest type of permanent magnet available commercially.
14 mar 2023 · The world's strongest magnet is a million times stronger than Earth's magnetic field. Learn more about sustainability and Google’s efforts at sustainability....
Learn how two researchers independently discovered the neodymium–iron–boron magnet, the most powerful permanent magnet in the world, in 1982. Find out how it revolutionized various industries and applications, and what are the challenges and opportunities for its future development.
A rare-earth magnet is a strong permanent magnet made from alloys of rare-earth elements. Developed in the 1970s and 1980s, rare-earth magnets are the strongest type of permanent magnets made, producing significantly stronger magnetic fields than other types such as ferrite or alnico magnets.
A team of MIT researchers tested a high-temperature superconducting magnet that broke the world record for the most powerful magnetic field strength ever produced. They hope to use this magnet to create a net-positive fusion reactor that could provide clean, carbon-free energy by 2025.
12 cze 2019 · Scientists have created the world’s most powerful superconducting magnet, capable of generating a record magnetic field intensity of 45.5 tesla. Only pulsed magnets, which sustain fields for a...
Dr Masato Sagawa invented and commercialised the sintered neodymium-iron-boron (Nd-Fe-B) magnet, which is the most powerful permanent magnet and enables cleaner energy technologies. Learn more about his discovery, development and applications of this innovative material.
