High Coercivity and Strength

High Coercivity and Strength

The most common type of rare-earth magnet is a neodymium magnet. It is the most popular type of rare-earth magnetic. Neodymium magnets are used in many different applications. For example, they are the most common types of permanent magnets used in medical devices. These magnets are strong enough to attract and repel objects. They can also be used as power for electrical equipment.


Because of their high coercivity and strength, neodymium magnets are considered permanent magnets. They are the strongest permanent magnets available and can last for many years. However, neodymium magnets can become demagnetized if exposed to high temperatures. This makes them ineligible for high-speed machines and many other applications. This is why it is important not to use neodymium magnetic magnets in high speed environments or near other magnetic materials.


Neodymium is one the strongest magnets known. Because neodymium’s magnetic field is stronger than any other metal, this is why it is so popular. Its magnetic strength is measured by gauss. The higher the grade, the stronger the magnet will be. The highest grade of neodymium magnets is N52. The magnet’s temperature rating is indicated by the letters following the grade. Standard temperature neodymium magnets have no designation, while high-temperature neodymium magnets are N52, SH, UH, and EH.


Neodymium magnets are very strong. The smallest cylinders are 8 millimeters in diameter and five millimeters long. They can produce more than 1700 g of force. Because neodymium magnets can generate more than ten times the force of ceramic magnets, they are becoming a popular choice for many applications. However, the force generated by these powerful magnets can be harmful. Larger neodymium magnetics have even broken bones.


Philtro Amdemrte and Rare Earth Magnets


Quartz Obsession’s podcast episode explores the past and importance of rare earth magnetics for our modern society. It also gives an overview of rare earth magnet production in China. China accounts for 87% of the magnet production worldwide. Japan is the other major source and sourcing the majority of rare earth magnets from Australian rare earth giant Lynas. This podcast is available to listen to on iTunes, Stitcher, and Stitcher.


Neodymium-iron-boron magnets


China is a world leader in the production and distribution of rare earth magnets. Contrary to lead and tin that are plentiful in the Earth’s crust rare earths don’t naturally appear in seams. China’s trade restrictions make it difficult to create rare earth magnets. This has prompted researchers to create powerful magnets free of rare earth metals.


Many rare earth magnets as well as neodymium magnetics are used in a variety applications. One study found that magnetic oxide nanoparticles are more easily taken up by cells. The researchers cultivated human stem cells in serum-free media and added nontoxic magnetic nanoparticles containing iron to the medium on a regular basis. It was observed to determine whether these magnets interfered with stem cell proliferation or prepotency.


Model U Traps


The Model U Trap uses a Rare Earth magnetic system to remove weak and ferrous magnetic contaminants from your product. The Model U Trap is made of 316-stainless sanitary steel and has ACME threads that can be installed into four-inch or three-inch lines. The Model U trap can be fitted with Xtreme elements, which offer increased performance at higher temperatures. It is recommended for removal of small and weak magnetic contamination from a variety of products.


Model T traps are specifically designed to minimize damage to your processing equipment. The trap is constructed with an reinforced plate and tube construction for increased durability and security. It can withstand a working pressure of 75 PSI. These traps are generally mounted upright, but may also be installed sideways or vertically. These traps also come with an deflector that allows you to see suspended solids that interfere with the flow.


Dura magnets


Rare earth magnets are strong and have a high coercivity. Rare earth metals are just as abundant in the Earth’s crust as lead and tin. However, they aren’t naturally occurring in the Earth’s seams, and their primary source is China. Numerous companies are working to create strong magnets despite recent restrictions from China on rare earth magnets.


Neodymium magnets were designed by General Motors in the 1980s. They are extremely durable and are utilized in many different industrial and consumer products. They are also used for jewelry clasps and magnetic holdsdowns. These magnets are the strongest and affordable rare earth magnets, and are able to withstand extreme levels of force. However, their price isn’t high, making them more prone to oxidation than samarium-cobalt magnets and it is therefore important to select an earth rare magnet carefully.


China’s dominance of rare earth magnets


China’s dominance in the production and sale of rare earth magnets is becoming a issue for Western companies. These materials are crucial in the creation of energy-efficient generators and motors, and a lack of them could leave businesses in limbo. Prices rose dramatically after China cut exports in 2011 of rare earth metals. Recently, a trade war between China and the United States and China has raised prices even more.
