Recycling Method of Sintered NdFeB Magnet Waste The waste recycling of NdFeB materials is usually divided into two directions: one is to separate and extract various elements, especially rare earth elements, in the NdFeB waste to prepare oxides or other compounds with a certain purity, which can be used as raw materials for different applications. [...]
Magnetic Material in Magnetic Separator Equipment The magnetic separator uses the magnetic difference between minerals for separation, which can improve the grade of ore, purify solid and liquid materials, and recycle waste. It is one of the most widely used and highly versatile models in the industry. one. Magnetic separators are widely used in mining, [...]
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 [...]
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 [...]
