In the process of transportation how to its magnetic shielding, how to pack the magnet magnetic magnets reduced to a minimum?
Here to teach you how to package the magnet and the weakening magnetic.
General magnetic material to do it is very difficult, shielding the magnetic completely most magnets for magnetic shielding processing but there are always some magnetic flux leakage.
Are generally in order to convenient transportation, good businesses try various means to wrap the magnet, but most of the poor packing method for magnetic shielding effect.
Here are several of the magnet better packaging method for your reference: 1, the use of packaging materials, high magnetic permeability material will magnets to make the most of the lines of magnetic force produced by a magnet through from the high permeability material, can impact on the magnet block!
To make the shielding effect is good, and high permeability material, usually with metal can!
2, iron has a magnetic field of magnetic shielding, the best way is to use iron box for big magnets, the magnetic force will decrease a lot;
3, iron boxes outside the bubble cushion packaging;
4, the overall cartoning, between packaging bubble cotton, made shielding plate;
Five, six with a pin on the carton surface test, no obvious attraction, or increase the carton;
6, when need shielding the magnetic field is very strong, shielding materials using only a single layer, is not short of shielding requirements, will happen is saturated.
At this time, one way is to increase the thickness of the material;
7, more effective way is to use a combination of shielding, a shield on another screen, leave any wind gap between them.
Inside the air gap can fill any non magnetic permeability material, such as aluminum.
Composite shielding shielding effectiveness than single shield is much higher, so the composite shielding to magnetic field attenuation to very low levels.
