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 [...]
Permanent Magnet Generators Offer Improved Performance for RE Production Permanent magnets have been used to provide the magnetic field in small to medium sized generators for many years. The use of these in large renewable energy (RE)generators may offer performance advantages for future utility-scale generators. Large (MW sized) permanent magnet generators (PMGs) are mainly found [...]
The Need Information for Customization Magnets In order Customization Magnets for us to effectively provide information and save your time, when you send customized inquiries, it is advisable that you provide the following information: 1.Material The magnet materials we offer include NdFeB, SmCo, Ferrite, Alnico, flexible magnets and so on. Please first confirm what kind [...]
Magnetizing or Magnetization In magnetizing the magnetic domains inside of a magnet are aligned with the magnetizing field. If the magnetizing field strength is high enough, all the domains will be aligned and the magnet is said to be magnetized to saturation. Magnetizing to saturation is usually recommended as only then are the magnetic properties [...]
History of Permanent Magnets Lodestones The history of permanent magnets goes back to ancient times. Records from early Greek, Roman and Chinese civilisations make reference to rare and mysterious stones called lodestones. These lodestones could attract each other and also small pieces of iron. When suspended from a thread it was noted that they always [...]
High Temperature Resistance Magnets Not all magnets are suitable for use in really high-temperatures, while some grades excel. Many applications, particularly within the manufacturing and engineering industries require magnets to be able to maintain their performance at incredibly high temperatures. Here you will find a selection of ferrite, alnico, samarium cobalt and special high-temperature neodymium [...]
Three environmental factors affect function of high temperature resistant magnet Environment temperature. Since sintered NdFeB has a negative temperature coefficient (αBr<-0.13%/°C, αHcj<-0.6%/°C), the instantaneous maximum temperature and the continued maximum temperature of the operating environment will cause different degrees of demagnetization of the magnet itself. Contains reversible and irreversible, rehabilitative and non-recoverable. Environment humidity. NdFeB [...]
New Trends of Rare Earth Permanent Magnet Industry in China Rare Earth Permanent Magnet Industry - Rare earth permanent magnet materials represented by samarium cobalt (Sm-Co) and neodymium iron boron (NdFeB) are the most permanent magnet magnetic materials in the world, and are widely used in many national economies such as information and communication, electronic [...]
Permanent magnet materials, also known as hard magnetic materials, are characterized by high anisotropy field, high coercivity, large hysteresis loop area, large magnetization field required for magnetization to saturation, and strong long-term retention after removal of external magnetic fields. Magnetic. In practice, the permanent magnet material operates in the second quadrant demagnetization portion of the [...]
Magnetrons Magnetic Assemblies, Sputtering magnetrons magnet materials, magnetic designs, FAQ 1, Help us designs Magnetrons Magnetic Assemblies - We do not make Magnetrons; we make the magnetic assemblies that enable these devices to operate effectively. In order to make a perfect magnet assembly, we would need to know the following: 1. What Type of magnetron is required? [...]
