Halbach Array, Halbach permanent magnet is a magnet structure. In 1979, American scholar Klaus Halbach discovered this special permanent magnet structure when he was doing electron acceleration experiments and gradually improved it, eventually forming the "Halbach" magnet. It is an almost ideal structure in engineering. It uses special magnet arrangement to enhance the field strength [...]
Surface magnetism refers to the magnetic induction intensity at a certain point on the surface of the magnet, and the unit is Gauss Gs or Tesla T (1T=10000Gs). The surface magnetism at different positions on the surface of the magnet is not the same. Generally speaking, "surface magnetism" refers to the center surface magnetism of [...]
Magnetic Induction B and Magnetic Polarization J Practice and theory have proved that when a ferromagnetic or ferrimagnetic substance is magnetized in a magnetic field, in addition to the magnetic field in the substance, because the magnetic moments of the atoms of the ferromagnetic substance turn to the direction of the external magnetic field, it [...]
Hysteresis Curve and Intrinsic Demagnetization Curve (B-H Curve and J-H Curve) Permanent magnet materials have two notable features, one is that they can be strongly magnetized under the action of an external magnetic field, and the other is hysteresis, that is, the material remains magnetized after the external magnetic field is removed. The relationship between [...]
Factors and Methods Affecting the Performance of NdFeB Magnetic Materials Since the advent of NdFeB permanent magnet materials, it has attracted much attention due to its superior magnetic properties. promote. We generally use remanence, coercive force and maximum energy product to measure the performance of magnetic materials. Remanence Br If the magnet is likened to [...]
Sustainable Recycling of Rare-Earth Elements from NdFeB Magnet Swarf: Techno-Economic and Environmental Perspectives Rare-earth elements (REEs) are increasingly susceptible to supply risks due to their limited geographical availability and growing demand in clean energy applications such as neodymium-iron-boron (NdFeB) magnets used in electric vehicles and wind turbines. When NdFeB magnets are produced, 6–73% of swarf [...]
Programs for Recycling Rare Earth Metals Have you ever wondered if you can recycle magnets? Previously, old magnets could not be recycled to reuse the rare earth metals inside them, but new methods have been developed that have made it worthwhile to reuse the material inside magnets. Magnets made with rare earth metals are used [...]
Recycling Neodymium Magnets Industrial neodymium magnets have become a critical part of our daily life and an important contributor to many advanced technology development. Majority of this rare-earth element is mined in China from monazite ((Nd, La, Ce)PO4) and bastnaesite (Ca(Ce, La, Nd)2(CO3)3 F2) ores; however, the mining and extraction processes can be expansive, complex [...]
Microbes Can Recover Rare-Earth Magnet Materials From Consumer Waste Recycling these materials critical into high-tech products could be crucial as the cost to mine and refine them continue to climb. Rare earth elements (REEs) such as neodymium and dysprosium are essential for technologies like solar and wind energy, advanced vehicles, and modern electronics like smartphones. [...]
ORNL licenses Rare Earth Magnet Recycling Process to Momentum Technologies The Department of Energy’s Oak Ridge National Laboratory and Momentum Technologies have signed a non-exclusive licensing agreement for an ORNL process designed to recover rare earth magnets from used computer hard drives. Rare Earth Magnet Recycling Process The patent-pending process developed as part of DOE’s [...]
University of Birmingham pilots rare earth metal recycling facility The University of Birmingham has been awarded £4m to set up a pilot facility to recycle rare earth metals from scrap. The pilot facility, based at Tyseley Energy Park in Birmingham, will focus on recycling magnets made from neodymium, boron and iron – metals often found [...]
