History of Permanent Magnets

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 [...]

How to Select the Magnet Shapes

How to Select the Magnet Shapes A magnet is an object that exerts either an attractive force or a repulsive force on another object. Good examples of materials with strong magnetic properties are iron, mineral lodestone and certain types of steel. One popular type of magnets is the rare-earth magnet. Commonly called a neodymium magnet, [...]

Three environmental factors affect function of high temperature resistant magnet

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 [...]
