Today said a lot of magnets used in friends are focus on one problem, ndfeb magnet magnetic can maintain how long?
Magnetic ndfeb magnet for how long?
What are the factors affecting ndfeb magnet demagnetization?
If kept in proper temperature, humidity and no strong external magnetic field, the radiation and other factors can influence the magnetic environment, its magnetic can almost can last forever.
The main factors influencing the magnetic ndfeb magnet we want to know;
Temperature and oxidation.
Working temperature range when the temperature exceeds the magnet, ndfeb magnet magnetic is weakened or even disappeared, when plating broken, the inside of the part by oxidation, ndfeb magnet magnetic will be weaken.
If they are not exposed to any of these conditions, the magnet will lose its magnetism, but the degradation is very slow, every ten years by one percent, so as long as the correct use, there is no worry about magnet demagnetization.
