Magnetization curve of magnetic material magnetic Hengdian Kim factory ---- magnetic material is made of ferromagnetic material or ferrimagnetic material composition, in the role of an external magnetic field H NdFeB prices, there must be a corresponding magnetization M or magnetic induction B, which varies with the magnetic field strength H curve is called the magnetization curve (M ~ H or B ~ H curve). Magnetization curve is generally non-linear, has two characteristics: magnetic saturation and hysteresis. That is, when the magnetic field strength H is large enough, the magnetization M reaches a certain saturation value Ms, continues to increase H, Ms unchanged; and when the material reaches the saturation value M, the external magnetic field H is lowered to zero NdFeB magnetic wholesale price, M is not set to zero local NdFeB magnetic, but changes along MsMr curve. Working state of the material corresponds to a certain point, this point is often referred to as the operating point M ~ H curve or B ~ H curve. 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% / ℃ NdFeB magnetic, αHcj <-0.6% / ℃), so use the highest instantaneous temperature environment and the sustained maximum temperature of the magnet itself will produce different 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.
