Apple's New Patent: Magnetic Design Free Shoelaces Apple publishes new patent for magnetic design, Apple Find My is the standard equipment for travel wearables According to the latest list published by the United States Trademark and Patent Office (USPTO), Apple has recently obtained a design patent, numbered US 11614108 B2. The patent does not involve [...]
If A Magnet is Constantly Doing Work, Will The Magnetism Be Weakened? This is an interesting misunderstanding. Magnets do not do work by consuming their own magnetism. Although the relationship between magnets and other magnetic substances seems magical, in fact, magnetic fields and springs are similar to a certain extent, so magnetism or magnetic fields [...]
Magnets May Hold The Key to A 'Wireless' Future Open the computer bag, put the mobile phone on the MagSafe charging board, open the cover of the Bluetooth headset; close the laptop, pick up the smart watch that is charging, and attach the ID card to the back of the mobile phone...unconsciously, the magnets have [...]
Good Magnets Are "The Rabble" Today, the reason why mobile phones, earphones and other devices can be made so compact is inseparable from high-performance permanent magnets, which are materials commonly known as "magnets". So how are these "magnets" made? Can we find stronger "magnets"? How are "magnets" made? "Magnet" is scientifically called a permanent magnet, [...]
Magnon Spins Observed in 2D Magnets According to the latest issue of "Nature" magazine, the collaborative research of several universities in the United States and Oak Ridge National Laboratory shows that the magnons in the magnetic semiconductor chromium bromide can pair with excitons, and the excitons will emit light, thus providing a new way for [...]
Magnets May Help Humans Breathe in Space Humans hope to colonize the Moon and land on Mars within the next decade. Or, at least that's the idea. However, there are still many technical issues to be resolved. How to plan a journey of more than 100 million kilometers (one way), which will take at least [...]
A Different Element Story: "Neodymium" in The Strongest Permanent Magnet From the grand challenges of 19th-century chemistry to humble, powerful technologies, Thornton and Burdett explain why neodymium was discovered twice by the two Carls as a twin element. In 1838, the Swedish chemist Carl Mosander isolated a new element, lanthanum, a metal that had been [...]
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 [...]
Rare Earths Members Neodymium (Nd) is the element after which Neodymium magnets are named. Praseodymium (Pr) is so close to Neodymium (Nd) that it is used in Neodymium magnets. Pr is right next to Nd on the periodic table and it's properties are very similar to those of Nd. So similar that about 25-35% of [...]
How Are Neodymium Magnets Made? Neodymium magnets are made by a sophisticated process that includes some very high-tech metallurgical methods comprising powder metallurgy and advanced process metallurgy. Dozens of process steps must be followed very precisely to make Neodymium magnets –also known as NdFeB -for the chemical symbols of Neodymium, Iron and Boron. Process variations [...]
Canada Want To Becoming A Rare Earths Supplier According to Canadian media reports, the Canadian Department of Natural Resources will hire a British company to provide market forecasts for the next 10 years for more than twenty important minerals used in the production of electric vehicle batteries, solar panels, wind turbines, and military equipment. The [...]
Slow Construction Of Global Rare Earth Projects According to Mining.com, Bloomberg News was quoted as saying that China ’s increase in rare earth production has caused confusion in the United States and Australia's plans to develop rare earth projects. This month, China announced that it will increase rare earth output in 2019 to 132,000 tons, [...]
Magnets Containing Small Amounts Of Rare Earth Elements Japan's National Institute for Materials Science and Tohoku Gakuin University have developed thin films of an anisotropic Sm (FE0.8co0.2) doped with boron that contain only small amounts of rare earth elements. The compound has 1.2 Tesla forcings, enough to be used in automotive motors. The film is [...]
Recycling Of NdFeB Magnets For Rare Earth Elements (REE) Recovery ABSTRACT NdFeB magnets currently dominate the magnet market due to their superior magnetic properties with maximum volume minimization. NdFeB magnets are composed of 25-35 wt. % rare earth elements (REE) along with ca. 1 wt. % B and the rest being transition metals (mainly Fe). [...]
