New alternatives may ease demand for scarce rare-earth permanent magnets Single crystals of CeCo3 synthesized by solution growth method. From computer hard discs and smart phones to earbuds and electric motors, magnets are at the forefront of today's technology. Magnets containing rare-earth elements are among the most powerful available, allowing many everyday objects to be [...]
Scientists create cheaper magnetic material for cars, wind turbines Scientist Arjun Pathak arc melts material in preparation for producing a new type of magnet. Karl A. Gschneidner and fellow scientists at the U.S. Department of Energy's Ames Laboratory have created a new magnetic alloy that is an alternative to traditional rare-earth permanent magnets. The new [...]
3D-Printed Magnets Made from Recycled Materials Using recycled materials to make magnets could allow companies to circumvent supply chain issues for sourcing magnetic objects. Permanent Magnets and Applications Group/IMDEA Nanoscience A processed powder from recycled magnetic material (left) can be used in a 3D printer to create magnets of arbitrary shape (right). The COVID-19 pandemic [...]
3D-printed Super Magnets From wind turbines and electric motors to sensors and magnetic switching systems, permanent magnets have many electrical applications. The production of these magnets usually involves sintering or injection molding. But due to the increasing miniaturization of electronics and the more exacting requirements, this places on magnetic components in terms of geometry, these [...]
3D Printing Magnetic Fields Is Now Possible With Polymagnet’s Maxels Theoretical physicist Michio Kaku has made it clear that the future belongs to mass customization, IoT and, further down the line, electromagnetism. While mass customization is made possible by 3D printing and the IoT will be made possible by embedded 3D printed electronics, it is [...]
3D printed magnetic polymer composite hydrogels for hyperthermia and magnetic field driven structural manipulation Magnetic hydrogels and soft composites have fueled the development of next generation biomimetic soft robotics due to their precise control and non-cytotoxic nature. Bare magnetic nanoparticles are difficult to regulate via remote controlling whereas, when these nanoparticles are arrested inside polymeric [...]
SPANISH RESEARCHERS DEVELOP 3D PRINTED MAGNETS MADE OF RECYCLED MATERIALS Insiders and analysts predict the 3D printing trends to watch in our latest series of articles focused on the future of 3D printing. Researchers at the IMDEA Nanoscience Institute, an interdisciplinary research center in Spain, have developed a new method of 3D printing magnets using [...]
Nanoscale textures found in 3D printed magnets may become potential information carriers In a study published in Nature Nanotechnology, an international team led by the Cavendish Laboratory at the University of Cambridge, UK, used advanced 3D printing technology to create magnetic double helices that, like DNA's double helices, twist around each other , which combines [...]
Tile Magnets Magnetization Process First, the reversible displacement of the domain wall When the external magnetic field is small, for the magnetic domain with the same or less external magnetic field with the same direction of spontaneous magnetization, this magnetic domain will expand due to the advantage of low magnetostatic energy; on the contrary, the [...]
