Although many users often use permanent magnets and may have purchased them more than once, they still do not know how to judge the quality of permanent magnets. This article will show you how to judge the quality of permanent magnets. You can refer to the following aspects.
First of all, from the perspective of size, the tolerance of the required size can be measured. Some outer diameters and thicknesses have serious positive and negative tolerances, which can be found by caliper measurement.

Then you can check the appearance of the magnet and check the surface treatment, if the color of the surface coating is poor, even if there are corners and edge collapse or bubbles, etc., you should be careful.
Then there is the Gaussian value. Many people know that the magnitude of the magnetic force depends on the GS value. Compare the actual GS value with the permanent magnet products or admitted samples of the same specification to see if the difference is big. It is best to compare the center point value of the permanent magnet. If conditions permit, it is best to Determine the magnetic flux.
The introduction is almost over. I believe that through the above introduction, you will have some ideas on the quality judgment of permanent magnets.
