What is Eddy Current Losses in Permanent Magnet Materials? Understanding and Minimizing Eddy Current Losses in SmCo and NdFeB Magnets Eddy current losses are a significant concern in rotating machinery, especially when using metal-based permanent magnets like Samarium-Cobalt (SmCo) and Neodymium-Iron-Boron (NdFeB). Core losses, which include both eddy current losses and hysteresis losses, must be [...]
Magnet Glossary A Air Gap An air gap is non-magnetic material present between a magnet and an attracted object or between two magnets attracting each other. It acts as a break in the magnetic circuit, weakening the magnetic hold. The air gap can be filled with air, wood, plastic, aluminum, paint, or any uneven surface. [...]

Electrolytic Hydrogen Decrepitation of NdFeB Magnets Electrolytic Hydrogen Decrepitation (EHD) is a method used for the fragmentation of NdFeB magnets. Here's how the process generally works: Preparation: The NdFeB magnets are first crushed or ground into coarse particles. These particles typically have a size ranging from several millimeters to a few centimeters. Electrolyte Bath: The [...]
Hydrogen Embrittlement Mechanism of NdFeB Magnet Hydrogen embrittlement in NdFeB (Neodymium Iron Boron) magnets can occur due to the presence of hydrogen atoms diffusing into the material's crystal lattice. This phenomenon can lead to reduced mechanical properties, such as decreased ductility and increased susceptibility to cracking or fracture. The mechanism typically involves the following steps: [...]
Hydrogen Embrittlement Failure of NdFeB Magnet Hydrogen embrittlement is a process by which hydride-forming metals become brittle, even fracture due to the penetration of hydrogen gas, and mechanical strength of relevant material will dramatically decrease because of hydrogen embrittlement. People have been studying how to prevent hydrogen embrittlement for over the past several decades. [...]

The term Rare Earth Magnets is [...]
What is Magnetic bracelets? Magnetic bracelets are accessories that are believed to have therapeutic benefits due to the presence of magnets. These bracelets typically consist of small magnets embedded in the bracelet's links or beads. The idea behind magnetic therapy is that the magnets can create a magnetic field that interacts with the body's natural [...]
Often wear magnet bracelets, cure diseases and strengthen health The earth is a big magnet, and human beings are not affected and affected by the geomagnetic field all the time. Like air, water and sunlight, geomagnetism is one of the indispensable elements for the survival of human life. When a person is exposed to a [...]
Why is the magnet bracelet nicknamed the bracelet that can cure diseases? The human body itself is a magnetic field. Although the effect is not strong, it is known from some data that the human body is still relatively sensitive to the magnetic field lines. From the detailed analysis, the appearance of the magnet bracelet [...]
What is the role of magnetic therapy bracelet 1. The magnetic therapy bracelet has the effect of ion penetration: We know that for the magnetic therapy bracelet, the germanium free electrons in it can penetrate through the skin, so as to neutralize the corresponding positive ions in the affected area, and then relieve the corresponding [...]
Summary of High School Physics Magnetic Field Knowledge Points Physics in high school is a deeper level than the knowledge learned in junior high school, because physics in high school involves more and more theoretical knowledge and formulas that need to be understood and memorized. So how can you study to improve your physics performance? [...]
