Hengdian Dongyang City, Kim Dae magnetic factory ---- how to shield or guiding magnetic field? Ferromagnetic materials can be used to shield the magnetic field, generally we use an ordinary iron. It should be noted that the thickness of the iron plate, if the thickness of less than iron in magnetic saturation, can only shield part of the field, the magnetic field lines emanating still be part of. The key guiding magnetic field forming a magnetic circuit that the choice of materials and the appropriate size and shape of the high permeability, reduce leakage magnetic NdFeB wholesale price, namely magnetic circuit yoke and pole pieces reasonable configuration. Hengdian Dongyang City, Kim Dae magnetic factory ---- What factors have major influence magnetic? Ambient temperature. Because NdFeB has a negative temperature coefficient (αBr <-0.13% / ℃, αHcj <-0.6% / ℃) NdFeB manufacturers address, different use of the environment and sustainable instantaneous maximum temperature of the highest temperature will be on the magnet itself degree of demagnetization, including reversible and irreversible, recoverable and non-recoverable. Humidity. NdFeB itself is prone to corrosion, oxidation, generally we take the form of surface treatment to protect the permanent magnet, but it does not fundamentally address the impact of humidity on the magnets at all. Environment more dry, the more long-term life of the magnet. Hangzhou NdFeB NdFeB role _ _ Kim Dae-magnetic factory trusted by Kim Hengdian magnetic plant.
