1. Q: The magnetic energy NdFeB magnets can for how long? A: NdFeB magnets have demagnetization and will not change under a high magnetic coercivity, the natural environment and the general magnetic field. Assume appropriate environment, even after prolonged use of high temperature magnets, magnetic magnets loss will not be great. So in practice, we often ignore the impact of time on the magnetic properties. 2. Q: magnet verticality, parallelism and roundness respectively? A: For example the outer diameter of the inner annular magnet D10-D30mm range verticality: 0.15mm Parallelism: 0.10mm roundness: 0.15mm outer diameter D30-D60mm verticality within the range: 0.20mm Parallelism: 0.15mm roundness : 0.20mm above is generally standard, any special requirements please specify in the order. 6. Q: The higher the table represents the magnetic properties of the strong magnet it? A: This question two possibilities to explain: 1) the same shape, size is also the same two magnets, magnetic table high magnetic strong magnet. 2) different shapes, different sizes, or two magnet high temperature magnets price, you can not simply watch a magnetic level to determine the level of magnetic magnet. The reason is the high aspect ratio of the magnet magnetic table (height to diameter ratio of the magnet) For high temperature magnet factory, high aspect ratio the greater the higher the magnetic sheet, namely directly to the magnetization direction of the surface area, the lower the surface magnetic; the magnetization direction of the larger dimension manufacturer of high temperature magnets, magnetic table is higher. Examples: NdFeB cylindrical D8x50mm, table magnetic: 4,600 gauss, NdFeB cylindrical D50x10mm, table magnetic: 3,300 gauss, obviously D50x10mm much stronger magnetic field than D8x50mm.
