Introduction to the performance method of distinguishing N35-N52 NdFeB strong magnet


NdFeB strong magnetic magnets are generally divided into N35/N38/N40/N42/N45/N48/N50/N52 and other grades. The most obvious difference between each performance grade is the difference in magnetic properties. For example, products of the same specification, The higher the performance grade, the better the magnetic performance of the product. However, the neodymium iron boron strong magnet is a kind of surface molecule and its active product. Therefore, the surface of the neodymium iron boron strong magnet must be electroplated, such as zinc plating, nickel plating, nickel plating copper nickel, epoxy resin, etc. Wait.

     Under normal circumstances, we don't have equipment to test the magnetic properties of products at any time around us, so how do we judge the product performance of a neodymium iron boron magnet? To be precise, there is no way to judge the performance of a magnet product without any testing equipment.

     Because they all look the same, you can’t tell what the results are. Maybe you’re looking for a few magnet suppliers, some quoted 0.08, some quoted 0.03, which creates a problem, why is that so cheap, isn’t it? Is it really the grade I want?

     In actual work needs, we often encounter the need to judge the magnetic properties of the product. If there is a Gauss meter, we can make a rough judgment based on the surface magnetic field of the product. Without the instrument, we need to use the unique product itself. To judge by magnetic conditions, for example, we first use a magnet to attract or repel each other, so we can judge the magnetic poles of the magnet product, at least the magnetic poles in a uniform direction. Magnet, you can feel the magnetic strength of the magnet product by the feel of the hand.
