Magnetized ferromagnetic demagnetization you can use the following ways: heated to above the Curie temperature, the material damage molecular Games Guancheng triangle magnet magnetic domains can eliminate all magnetic. The material is placed in a magnetic field changes repeatedly, and intensity of the H field than the coercivity of the material, and then slowly removing the material field Guancheng triangle magnet company phone, or slowly the intensity of the magnetic field to zero . This is demagnetisers equipment and credit card demagnetization, and a cathode ray tube principle demagnetization coils. If the magnet is placed in a magnetic field strength greater than the coercive force of the reverse magnetic field, the magnet may be part of the magnet demagnetization Guancheng triangle where the good, but there may be a reverse magnet magnetized. Hammering or impact: Disturbance mechanics will disrupt the magnetic domains Guancheng triangle magnet Which is good service, it will reduce its magnetic part. The main impact of the magnetic properties which the 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, 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. How to measure the magnetic properties of high and low? There are three main parameters: remanence Br (Residual Induction), units of Gauss, is a measure of magnetic strength of the external magnetic field can provide the parameters; the coercive force Hc (Coercive Force), unit Oersteds, is a measure of the anti-demagnetization parameters; magnetic energy product BHmax, units Gauss-Oersteds, is the characterization of how much energy can be stored in a physical quantity.
