NdFeB magnets - magnets in the 'Magneto' NdFeB magnets are permanent magnets an artificial, permanent magnets to date with the strongest magnetic force, is the commercialization of the highest performance magnets, known as the "magneto" magnetic energy with a high maximum energy product higher than 10 times more than the ferrite. Machining performance itself is also quite good NdFeB magnets. Working temperature up to 200 ℃. And its hard, stable performance, good price, so its application is extremely broad. But because of its chemical activity is very strong, it must deal with its surface coating. 12. Q: magnet magnetic suction together will increase after it? A: magnetic attraction force will increase superimposed flashlight magnet, but it is not a multiple of the relationship. 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 magnetic material lamps, to meet this requirement of the material is an iron-nickel alloy, a material with high magnetic permeability. Please note that the iron gap between the magnet and the need to leave, you can fill in the gap to make any non-permeability material support. For larger size magnet, only a single layer shielding materials, it is difficult to achieve complete shielding requirements magnet magnetizing fixture, then the magnet, one method is to increase the thickness of the iron plate, but more efficient method is to use a combination of shielding, the a shield in the other shielding body, leave some gap between them. Shield in shielding effect is much better than a single shield, thus shield in a magnetic field can be attenuated to a very low level.
