Magnetic Field Shielded

How is magnetic field shielded ?

   In order to avoid the excessive magnetic field that causes unnecessary trouble in the transportation process, xingchuang magnetic industry recommends the following methods:

1. General shielding method: iron plate shielding magnetic field.

2. Magnetic shielding requires high permeability material. The material that meets this requirement is iron-nickel alloy, which has a high permeability.

3. When the magnetic field that needs to be shielded is very strong, only the single layer of shielding material is used, not the shielding requirement, which is the saturation. At this point, one method is to increase the thickness of the material.

4. The more effective method is to use combination shielding, to put a shield in another shield and leave a gap between them. The air gap can be filled with any non-permeability material, such as aluminum.Combined shielding is much more effective than a single shield, so combination shielding can attenuate the magnetic field to a very low degree.
