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% / ℃), so use the environment Instantaneous maximum temperature and duration of the maximum temperature of the magnet itself will have different degrees of demagnetization, including reversible and irreversible, recoverable and non-recoverable. Humidity. NdFeB itself is prone to corrosion, oxidation Which Ningbo strong magnets, 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. Which environment more drying Ningbo strong magnet, the more long-term life of the magnet. Converting electrical parameters large magnetic Hengdian gold factory ----- soft magnetic materials and device parameters in the design process when the device is soft, first determine the voltage - current characteristics of the device according to the requirements of the circuit. Voltage - current characteristic of the device is closely related to the geometry and the magnetization state of the magnetic core. The designer must be familiar with the magnetization process material and take relationship between magnetic parameters and the device converts the electrical parameters of the grip material. Design soft devices typically involves three steps: correct selection of magnetic materials; reasonably determine the geometry and dimensions of core; The magnetic parameters required to simulate the core of the work of the state to give the corresponding electrical parameters. _ Kim Dae-magnetic magnet wholesale factory contact information (online consultation) _ Ningbo magnet by large magnetic Hengdian gold plant.
