Magnet delivery is after magnetization, the requirements for magnet packaging is also extremely important, looks ordinary carton box but hidden mystery. The first thing we need to do is to degausse the magnet, and the degaussing is not actually making the magnetism disappear. It's just a seemingly unnecessary packing magnet on the box that makes us think the magnet is "demagnetized"; In fact, the magnetism of the magnet is still there, but the magnetic field of the magnet packaged inside is recombined, and the magnetic insulation material is used to achieve demagnetization and demagnetization, so as to pass some magnetic security checks.
The packaging of demagnetization magnet is also determined by the magnetism of the magnet; Generally, some strong magnetic magnets are isolated directly with iron sheet, fixed and then put into the carton with pearl cotton bag. It can achieve certain demagnetization effect. There are a few caveats to the package though. Packaged magnets will have an impact force that attracts each other, because strong magnets are sintered from rare earths, which have lower hardness and toughness and are more fragile. Therefore, packaging requires placing a plastic sheet on the surface to avoid direct magnet attraction and collision, or
