How To Identify The Quality Of A Sintered NdFeB Magnet? Due to its cost-effectiveness, the sintered Nd-Fe-B neodymium magnet is widely used in many fields. Its applications include PC hard drives, magnetic resonance imaging (MRI), electric cars, magnetic levitation technique and consumer products like DVDs, mobile phones and speakers. Since it is required in nearly [...]
Can Magnets Lose Their Magnetism? The magnetic field of permanent magnets is not so permanent. Materials that are known as permanent magnets consist of magnetic domains, where electrons are aligned in pairs within atoms. Magnetism is weakened as a result of damage to this alignment caused by heat and electromagnetic fields. Samarium-cobalt magnets lose nearly [...]
Electro Permanent Magnet (EPM) is the newest technology, featuring 95% energy saving and totally safety compared with traditional electromagnet method. Only needs power during MAG and DEMAG periods. During working, no power supply is required. Driven by magnetism, MPCO’s magnetic solutions encompass a wide range of industrial sectors, including magnetic lifting system, magnetic clamping system, [...]
Standards and Regulations for Neodymium Magnet Use Though neodymium magnets have a strong magnetic field, they are very brittle and require special handling. Several industrial monitoring agencies have developed regulations regarding the handling, manufacture, and shipping of neodymium magnets. A brief description of a few of the regulations is listed below. Standards and Regulations for [...]
Introduction of Magnetic Force of NdFeB Magnet The largest and most important part of a magnetic resonance imaging system is the magnet. The unit that marks the grade of this magnet is called Tesla. Another common unit of measurement applied to magnets is Gauss (1 Tesla = 10000 Gauss). At present, the magnets used in [...]
Surface Coating Technology Increases the Life of NdFeB Magnets At present, China's rare earth NdFeB production has formed an industrial system, and the output has accounted for more than 80% of the world's total output. However, China's production of high-end NdFeB products is lack of competitiveness, which has become a bottleneck restricting the development of [...]
The Role of Samarium and Other Elements in Sintered NdFeB Sintered neodymium iron boron, as its name suggests, is an alloy material consisting of Nd2Fe14B, a compound consisting of three elements: neodymium Nd, iron Fe, and boron B. But sintered neodymium iron boron is not a single phase. .1Fe4B4 phase) and Nd-rich phase (also known [...]
How to Select NdFeB Powerful Magnets With the development of science and technology, Nd-Fe-B magnets are more and more widely used in the industry, such as high-speed aircraft, energy vehicles, electronic digital and so on. The increasing demand for magnet manufacturers is also increasing, which makes the market of magnets become a mess, fish eye [...]
Brief Introduction to Neodymium Magnet Materials The third generation of rare earth permanent magnet, Neodymium Iron Boron (Neodymium magnets), is the most powerful permanent magnet in modern magnets. Neodymium Magnet Materials The highest Remanence (Br) of Neodymium magnet1 is 3.8 times that of ferrite magnet, 1.1 times of that of Aluminum Nickel cobalt [...]
100KG Heavy Lifting Permanent Magnetic Lifter, NO Electricity Required PML-100 Lifting Capacity: 100kgs You might chrome or black holder depending on current stock. General Information Permanent Magnetic Lifters with strong magnetic path produced by NdFeB are mainly used for connecting component during lifting and handling operation. They can hoist moving iron block, cylindrical and other [...]
Magnetic Theory and Design 1. Can you explain the difference between coercive force and intrinsic coercive force? The intrinsic coercive force is the coercivity of a magnet material in a closed circuit configuration. A closed circuit configuration means the magnet does not have any exposed poles. Some examples of a closed circuit configuration are a [...]
Magnetic Magnetization Patterns Isotropic magnets, such as Bonded Nd-Fe-B, are unoriented and have no preferred direction; therefore it is possible to magnetize them in any direction. Almost all other materials are anisotropic and have a preferred direction of magnetization. They will exhibit the best magnetic properties when magnetized in the direction of the grain. Higher [...]
