Many customers are not clear about their needs for purchasing magnets. Many times they know the size and the brand, or know the purpose and don’t know how many sizes are appropriate. Magnets have different sizes, shapes and performance grades. These three key considerations may be It is helpful for suppliers to help recommend suitable magnets. Let Xiaochen introduce it to everyone.
The following three methods can help you determine how to choose the right magnet:
1. Size and shape
When it comes to magnets, a larger size does not necessarily mean stronger magnetic properties. There are many other factors that determine the strength of the magnet, such as the material itself, thickness, etc., but the size and shape still need to be considered.
2. Performance grades
The usual performance grades of neodymium iron boron magnets are N28-N52. Commonly used in the industry are N35 and N38. N52 is the strongest in theory. The higher the grade, the better the performance of the magnet.
3. Materials and uses
The type of magnet can also be different. Permanent magnets do not need energy, because they have natural magnetic fields. They are divided into two categories. One type is used for simple adsorption, so generally the performance requirements of the magnet will not be too high; the other type is magnetic field for work, for example The magnet on the motor needs to perform work through the magnet's own magnetic field, so the performance of the magnet is very high in this case.
