Surface Magnetism Field 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 [...]
Magnetic Moment The generation of the magnetic field can be divided into two aspects: one is based on the moving current (electromagnetic induction), and the other is based on the spin of the basic particles of matter. The first is the magnetic effect of current that we are more familiar with, which is the magnetic [...]
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 [...]
Permanent magnets in Apple's magnetic wireless charger Since the iPhone 8 in 2017, Apple has added a wireless charging function to all iPhone models, which is similar to other mobile phone wireless charging methods. It starts charging when placed on a wireless charger. This wireless charging relies on the transmitter coil and Accepting the alignment [...]
Magnetization direction and orientation direction The magnetism of permanent magnets mainly comes from its crystal structure that is easily magnetized. It can obtain extremely high magnetism under the action of a strong external magnetic field, and its magnetism will not disappear after the external magnetic field disappears. Therefore, "magnetization" is NdFeB A key step for [...]
The special metal bond structure of iron cobalt nickel leads to their paramagnetism? Yes, metals such as iron cobalt nickel have special electronic structures that allow them to be strongly magnetic. In these metals, each atom has unpaired electrons in its outer shell that can interact to create magnetism. Such magnetism is called paramagnetism because [...]
This is a about magnet article by AI writer A magnet is a substance that generates a magnetic field and attracts or repels objects. It is made of a special metal alloy, usually a mixture of iron, nickel, cobalt, and some other metals. Between these metals exists a special electronic structure called spin. When a [...]
U.S. worried about export of neodymium magnets restricted by China As an magnet practitioner, I do not have personal opinions or beliefs. However, I can provide information about neodymium magnets and their significance. Neodymium magnets are among the strongest magnets known, and they have a wide range of applications in various industries, including transportation, energy [...]
Neodymium magnets, why should the United States worry about getting stuck? The contemporary "Permanent Magnet King" neodymium magnet has become the protagonist of hot discussions these days. This is because the United States issued an order and announced that it will "not restrict the import of neodymium magnets mainly from China." The reason mentioned that [...]
Rare earth elements and key minerals will be the next geopolitical wrestling field A few days ago, an "Economic Survey Report" released abroad emphasized that the transition to clean energy means that the demand for key minerals (CM) will increase significantly. Supply of critical minerals and rare earth elements (REEs) will be the next "geopolitical [...]
US and Europe plan to "decouple rare earths" from China, G7 Group Buyers Club Goes Global to Buy Minerals "The EU and the United States have taken an important step toward each other in the trade conflict over U.S. green technology subsidies." German "Der Spiegel" weekly reported on the 12th that U.S. President Joe Biden [...]
U.S.-made rare earths will skip China and supply Japan By Masumi Suga, Bloomberg News (Bloomberg) - The sole U.S. producer of rare earths has reached a deal to ship output from its new processing plant to Japan, a further push by the U.S. and its allies to reduce China's role in their critical supply chain. [...]

Why are Samarium Cobalt and Neodymium Magnets Called Rare Earth Magnets? There are seventeen rare earth elements– fifteen of which are lanthanides and two of which are transition metals, yttrium and scandium, that are found with lanthanides and are chemically similar. Samarium (Sm) and Neodymium (Nd) are the two most commonly used rare earth elements [...]
