How to distinguish NdFeb magnet N35-N52 performance

If the magnet I ordered is N48 performance. So how do I know if it's really N48? I believe there are a lot of friends confused about this, Today, I talk about how to distinguish the performance of magnets.

First, you need to know neodymium magnets have different level, such as N grades: N35 N38 / N40 N42 / N45 / N48 / N50 / N52, etc. Attached is the data table of NdFeb with different grades of performance.

Maybe you're wondering what's the relationship between magnet grade and magnet strength?

The performance parameters between different grades are different, but the main difference is in the magnetic property, the higher the performance grade, the better the magnetism of the product.

So how to distinguish the strength of different grades of NdFeb magnet products? If there is no detection equipment, it is basically impossible to accurately judge the performance of the magnet.

In practical applications, for magnetic products, we often need to understand their performance. We can use the unique magnetic conditions of the product itself to judge, the following are several ways to distinguish different grades of NdFeb magnets.

First, the magnet to correspond to the attraction or repulsion, from which we can judge the magnetic pole of the magnet product, at least can judge the unified direction of the magnetic pole.

Second, translation of two magnets, with the feel can feel the magnetic strength of the magnet product.

Third, use a magnet to separate a board adsorption of an iron thing, and then let the magnet slowly leave the board, see how far, iron objects fall from the board, which distance, which is strong magnetic.

Fourth, the company allows the case of the best to buy magnetic testing equipment, such as Gauss meter, or flux meter, convenient more accurate detection.

Warm tip: If the number of magnets you need is very large, please send samples to the factory to test the real performance, to ensure the accuracy of product performance, such as N35 and N38, in fact, the magnetic difference is very little, the use of the process may not be able to distinguish, but the price will be different, when the quantity is much later, you will find a performance difference, the cost will be a lot of difference.
