Neodymium magnet is still the most powerful and frequently used rare earth permanent magnetic material nowadays. Neodymium magnet can be classified to into sintered Neodymium magnet, bonded Neodymium magnet, and hot pressed Neodymium magnet in accordance with the manufacturing process. Each form has their different magnetic properties, then their overlapped application scope is less and…
All material can be classified into ferromagnetism, ferrimagnetism, paramagnetism, diamagnetism, and anti-ferromagnetism according to their magnetism behavior and bulk magnetic susceptibility. Ferromagnetic and ferrimagnetic material can form permanent magnet or be attracted to magnets. Paramagnetic materials are weakly attracted to the permanent magnet. Paramagnetic materials can become very weak magnets under the action of magnetic…
Multipole ring magnet is infinitely a preferred path for rotating machinery and magnetic coupling device compared with traditional splicing several arc magnets. Besides polar anisotropic ring magnet which made by multipole orientation technology, radial ring magnet, which also known as radially oriented ring magnet, is the most common and mature solution to produce multipole ring…
Sm2Co17-based magnets are still playing an irreplaceable role in the permanent magnet industry due to its unique high temperature magnetic properties and superior magnetic stability, then it always serving to the high-speed motors, electronic communication, and aerospace. High energy product magnets are the important basis to accelerate miniaturization and high efficiency of the device. Thus,…
Permanent magnet motors applied the permanent magnet as the excitation source. In addition to reducing power consumption, operational performance of the motor can be also enhanced. Permanent magnet motors utilize several kinds of permanent magnetic materials, including AlNiCo magnets, ferrite magnets, and rare earth permanent magnets. AlNiCo magnets were developed in 1930s and remarkable for…
Innovations brought by 5G technology would have more impacts on our daily life in the Post-epidemic Period, include intelligent security, self-driving technology, VR/AR, and telemedicine, thus it could be argued that 5G technology are becoming an important engine for national economy development and social informatization. Besides 5G Samarium Cobalt magnets, 5G microwave ferrite has also…
Apple Inc. launched MagSafe accessories with their new iPhone 12 series. In fact, MagSafe is a brand of breakaway magnetic charging cables for the MacBook before, and now extend to the iPhone 12 series. Teardown reports showed that an assembly which includes a MagSafe magnet array and alignment magnet is embedded in the back of…
Apple Inc. launched their iPhone 12 series recently. Magnetic attachment wireless charging and MagSafe accessories attracted the most attention and analysis. Actually, Apple Inc. has been already utilized magnetic attachment wireless charging in their iWatch and Apple Pencil, then also obtained positive market feedback. As a new type of energy transmission technology, wireless charging technology…
Either researchers or magnet manufacturers have been put many efforts into the recycling of bulk sintered Neodymium magnet wastes due to the concerns of environmental protection and rare-earth resource supplies. The total rare-earth content in waste magnets is certainly around 30wt% which much higher than most natural mines. In the meanwhile, waste magnets are usually…
