Fundamentals, Applications and Techniques of Magnets and Magnetic Materials A magnet is an object that can generate a magnetic field and is widely used in various fields. The magnetic material is a class of magnetic materials, including iron, nickel, cobalt and so on. ONE. Basic principles In physics, electric currents and moving charges create magnetic [...]
The Three Big Secrets of Magnetic Phenomena Magnets and magnetism are ubiquitous in our daily lives, helping us find our way in unfamiliar wilderness and keeping the refrigerator door shut at home. In addition to these common examples, magnetic phenomena can sometimes play a role in certain situations, such as in MRI scanners, where magnetic [...]
Why The Flame Can Be Affected By Magnetic Field - Plasma in the Outer Flame. Magical plasma We all know that matter has three common states: solid, liquid, and gas. However, in addition to these three states, there are also plasma states, liquid crystal states, and so on. If we continue to heat the gas [...]
Flames Are Also Magnetic, Can They be Attracted by Magnets? Some time ago, a video was circulated on the Internet, someone used an electromagnet to change the shape of the flame. As shown in the animation above, when the electromagnet is energized, a magnetic field is generated in the central gap, and the flame becomes [...]
National Standard Evolution and Common Preparation Methods of Sintered NdFeB China's rare earth permanent magnets have the strength to reach the top of the world's magnetic materials market. This is not only because my country is rich in rare earth resources and undertakes the huge production volume of global permanent magnets, but also because the [...]
Grain Boundary Diffusion Technology With the wide application of sintered NdFeB materials in modern industry and electronic technology, especially in the fields of new energy vehicles, industrial robots and mobile intelligence, it is required that NdFeB products be developed towards lightness, thinness, miniaturization and high energy. The requirements for energy product, coercive force and thermal [...]
Common Magnetic Circuit Structure The use scenarios of NdFeB permanent magnets are roughly divided into adsorption, repulsion, induction, electromagnetic conversion, etc. In different applications, the requirements for magnetic fields are also different. The space structure of 3C products is extremely limited, and at the same time requires high adsorption strength. The space structure does not [...]
High Abundance Cerium Magnets With the continuous expansion of the application field of sintered NdFeB and the rapid growth of output, the corresponding rare earth resources have also been exploited in large quantities. Various rare earth elements in rare earth ores are symbiotic, but in the preparation process of NdFeB, mainly praseodymium Pr and neodymium [...]
Cutting process of sendust magnetic ring The sendust magnetic ring is a ring-shaped magnetic conductor, which is one of the most widely used magnetic rings. Simply put, the sendust magnetic ring is composed of aluminum-silicon-iron. Internationally, the sendust magnetic ring can be called It is a magnetic powder core. Its magnetic core loss is much [...]
Low frequency of air conditioner is changed to high frequency, magnetic powder core ushers in demand At the beginning of 2020, in addition to the medical market, production in many other industries was sluggish and demand was urgent. Especially in the home appliance industry, due to the objective reasons of the home economy, the demand [...]
Japanese researchers successfully produced "magnetic microtubules" inspired by magnetotactic bacteria The research team of Assistant Professor Inaba and Professor Matsuura Kazunori of the Department of Chemical Biology, Faculty of Engineering, Tottori University, Japan, and the research team of Associate Professor Kakugoaki and Professor Sada Kazuki of the Graduate School of Science, Hokkaido University, through By [...]
Permalloy Foil with Magnetic Noise Suppression effect at low frequencies Contributing to weight and thickness reduction of devices used for electric and autonomous vehicles Daido Steel Co., Ltd. (President: Takeshi Ishiguro) has launched a new product "STARPAS®-50PC2S", permalloy*1 foil this month, which has excellent performance in suppressing EMC noise*2 (mainly magnetic noise) at low frequencies [...]
