Hengdian Kim Dae-magnetic NdFeB magnet factory ----- What precautions NdFeB magnets because of superior magnetic attraction, in the course of the workplace should ensure a clean install and use, otherwise easily absorbed iron attract objects thereto debris, such as nails, too many small particles of iron powder will affect its use; Material Features NdFeB magnets are hard and brittle, and the suction force of up to 600 times its own weight, easy to pull collision damage. Procedure for small size magnets should be taken to avoid damage bump, magnets and more for large sizes to note that personal safety and protection. Hengdian Kim Dae magnetic field strong magnet factory ---- how to shield powerful magnets or magnetic NdFeB magnets are particularly big headphones speaker magnets, sometimes interfere to some electronic products. In air transport electromagnetic products have certain restrictions. Now in the domestic air transport of magnetic products are prohibited in the international transport of electromagnetic products also have very strict regulations. We have a way to get these objects magnetic field does not affect or reduce the effects of it? Yes, that is shielded it. Our common ordinary iron magnetic shielding. Higher magnetic shielding requirements requiring high magnetic permeability material, the material to meet this requirement is an iron-nickel alloy, which material has a high permeability. When the need to shield the magnetic field is strong magnet speaker size, with only a single layer shielding materials, not reach the shielding requirements, that saturation will occur. In this case, one method is to increase the material thickness. But more efficient method is to use a combination of shielded speaker magnet Buying, a shield over the other shield body, leaving an air gap between them. Can be filled with any non-permeability material support to do within the gap, such as aluminum. Much higher than the shielding effectiveness of a combination of shielding single shield, so the combination of weak magnetic shield can be reduced to a very low level.
