12. Q: magnet magnetic suction together will increase after it? A: magnetic attraction force superimposed will increase, but not the relationship between multiples. 13. Q: a magnet magnetic magnets of the same size superimposed same? A: Both magnetic roughly the same, but because there is a gap, there will be some loss of magnetic superimposed between the magnets. 14. Q: How magnet separated from the magnetic shield? A: usually an ordinary iron to shield the magnetic field, the magnetic shield that require high permeability material, to meet this requirement is an iron-nickel alloy material, this material has a high magnetic permeability. Please note that the iron gap between the magnet and the need to leave, multi-polar magnet specifications, can be filled in the gap to make any non-permeability material support. For larger size magnet, NdFeB multipolar magnetization, only a single layer shielding materials, it is difficult to achieve complete shielding requirements, multi-polar magnetizing magnetic ring, then, a method is to increase the thickness of the iron plate, but more effective method is to use a combination of the shield, a shield in the other shielding the body, leaving a certain gap between them. Shielding effect of shield in the shield is much better than a single, multi-polar magnetic charge, so a combination of magnetic shielding can be attenuated to a very low level. Magnets storage and transport What precautions? Pay attention to the indoor humidity must be maintained in a dry level. Do not exceed room temperature; when the product is stored may be appropriate oiled black block or blank state (usually oil can); plating products should be vacuum sealed or cut off the air for storage to ensure corrosion resistance coating; magnetizing product should pull together and packing storage, so as not to pick up other metal body; magnetizing product should be stored away from the disk, magnetic cards, magnetic tapes, computer monitors, watches and other objects sensitive to magnetic fields. Magnet magnetization state should be shielded transport, especially air transport must be completely shielded.
