7.What is the factor that influence the magnetic performance?
It is temperature. Because the sintered NdFeB magnets are very sensitive to the working temperature, both the temporary highest temperature and continual highest temperature will have different effects on demagnetization, including reversible and irreversible, retrievable and irretrievable.
8. What is the cope of working temperature of Neodymium magnets?
The limitation of temperature of NdFeB magnets caused a series of research in order to adapt the magnets to different requirements of temperature, please refer to our catalogue of performances of different grades of magnets. Before you choose the magnets, please confirm what is highest temperature you require for the magnets.
9. How to isolate the magnetic power?
In general, we use the iron plate to isolate magnetic power. And the Fe-Ni alloy is a good choice for the job. When you use single material, it usually fails to do it. Then there are two solutions for this situation. First, you need to thicken the material. The more efficient way is use combination to isolate the power, that is, you put one material inside another one, between the gap of the two materials, you fill it with non-magnetize material like AL. The combination is much more useful than the single material, thus it can reduce the magnetic power to the lowest.
10. The storage and transportation of magnets.
You need to keep it dry and ventilated to store the magnets, otherwise the wet p lace will cause rust of the magnets. Do not exceed the maximum working temperature; If uncoated magnets, you can put oil to avoid rust. And if for the magnetized magnets, you should keep it away from magnetic disk, magnetic card, magnetic tape, calculator, watch, and anything that is sensitive to magnetic power. The material is fragile, you should be careful during the transportation, plating or installing. If it is not properly used, or badly crashed, the magnets will be damaged or cracked. If you ship the magnets by air, you should isolate the magnetic power thoroughly.
11. Attention for applying the magnets.
You should keep the environment neat and clean, otherwise the magnets are easily absorbing the scrap iron or other small things, that will have effect on working of magnets. The characteristic of neodymium magnets is hard and fragile, and the sorption power is 600 times than its own weight, it is easily absorbed and damaged. So you should be careful when use the small sizes of magnets. As to the big sizes, you should be careful yourself when you use it. It may break your finger or hand.
