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 [...]
Take you to know how magnets are produced Due to the wide variety of magnets, the usual manufacturing method is to sinter rare earth permanent magnets. For raw materials such as samarium cobalt and neodymium iron boron, sintering is carried out under vacuum or a protective atmosphere, post-treatment and mechanical processing, and the processing components [...]
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 [...]
