The performance of a ferrite multi-pole magnetic ring cannot be measured by the surface magnetism of a product, nor can the performance of a product be tested from the surface magnetism of a ferrite multi-pole magnetic ring, because the ferrite multi-pole magnetic ring itself It is a product of magnetic polarization. The same product will detect different surface magnets due to the number of magnetized poles. Therefore, to test whether a ferrite multi-pole magnetic ring is qualified, it must pass the product performance test.
When selecting a multi-pole magnetic ring, try to choose a larger magnetic ring and higher characteristics, so that its characteristics are better, and the magnetic ring with good characteristics is more durable, and it is not prone to heating or saturation problems. If you are not sure For the characteristics of the magnetic ring, a magnetic ring with a large outer diameter, a long length, and a small inner hole can be selected first, because it contains more materials, and the more materials it contains, the better the natural effect.
