All Knowledge About Magnetic Jewelry Clasps What are Jewelry Clasps? Jewelry clasps are an essential part of jewelry that is often overlooked. Not all pieces of jewelry require clasps. However, a good number do. Some types of jewelry that require clasps include necklaces, bracelets, and ankles. These clasps allow you to wear or take off [...]
Operating Point, Load Line and Permeability Pc of Permanent Magnet The permanent magnet works in the open circuit state. Since the magnet in the open circuit state is under the action of the demagnetization field, the magnetic induction intensity of the permanent magnet in the working state is not at the Br point in the [...]
Anisotropy of Permanent Magnet Shape and Demagnetization Field and Demagnetization Factor Make the permanent magnet into a certain shape. Take the block magnet in the following figure as an example. If you measure the magnetization curve in the open circuit state along the x, y, and z directions of the magnet, you can find that [...]
Safety Essentials for Parents: Small Magnet Safety Reminder Small magnet safety reminder Parents and caregivers are advised to exercise caution when exposing children to products with small magnets. These can be life-threatening if swallowed accidentally. Small, powerful magnets are also increasingly used in novelty items. Younger kids may mistake these colorful magnets for candy and [...]
The Origin of Magnetism and Negative Temperature Characteristic in Finite Level Magnetic System The magnetism of matter is a deceptively simple problem that is actually quite subtle. In history, magnetism was discovered by humans very early. But it is strange that such "simple" magnetism cannot be described by classical physics, which seems so powerful! Specifically, [...]
How to Wire The Magnetic Proximity Switch, Principle and Characteristics? What is the working principle and characteristics? The magnetic proximity switch is a kind of proximity switch. The magnetic proximity switch is one of many types in the sensor family. It is made of electromagnetic working principle and advanced technology. It is a position sensor. [...]
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 [...]
Analysis of Downstream Industry of Magnetic Materials Magnetic materials are widely used in the fields of new energy electrical appliances, power communication equipment and military aerospace, including motors, consumer electronics, generators, new energy sources, etc. At present, the magnetic material industry is in a stage of rapid growth. There are BYD, Gree Electric Appliances, ABB, [...]
Analysis of Midstream Industry of Magnetic Materials With the further favorable national policies, more and more demand will be released. The magnetic material industry is closely connected with the upstream and downstream resources of the industry to fully grasp the needs of users, which greatly enriches the application scenarios of the industry and further promotes [...]
Analysis of Upstream Industry of Magnetic Materials Rare earth materials include titanium alloys, rhenium, rare earth magnesium alloys, ferric oxide, etc. The upstream of magnetic materials is mainly the separation, mining and smelting of rare earth ores. Rare earth ores mainly exist in the form of minerals in the crust, and there are mainly three [...]
In 2023, The Market Output of Magnetic Material Industry Will Continue to Increase Magnetic materials, also known as magnetic functional materials, usually refer to ferromagnetic materials, which are magnetically ordered materials with ferromagnetism or ferrimagnetism and practical application value. A fundamental difference between them and other materials is that they are sensitive to external magnetic [...]
China Considers Banning Some Rare Earth Magnet Technology Exports According to "Nikkei Asia" reported on Thursday (April 6), Chinese officials plan to revise the list of technology export restrictions. The revised content will prohibit or restrict the export of technology for processing and refining rare earth elements, and also proposes to prohibit or restrict the [...]
