Neodymium And Ferrite Magnets Manufacturer & Supplier 
Magnetic force of the magnet is not enough. Have you considered stacking it? Today, Mr. Courage Magnet brings you articles with different levels of neodymium magnets stacked together, which are not very practical.
Due to the high cost of manufacturing N52 NdFeB magnets, the average cost is about 150-300% of N35.
However, the magnetic force provided by N52 NdFeB magnets is only increased by about 20%. Usually, for this kind of requirement of increasing the magnetic force on the surface, it is recommended to increase the thickness of the magnet, or to use the stacking method to carry out the relevant tests or applications. According to the experience, if the thickness is 1~5mm, the thickness can be increased by 30~40% (the cost is about 30~40% higher on average), and the Gauss value of the surface magnetic force can be increased by about 20% (according to different specifications for actual testing).
The following picture shows the dia 30mm high strength neodymium cylindrical magnets
Some customers need high magnetic force when the magnet size and thickness cannot be increased due to lack of design and space. In this case, high grade NdFeB magnets, such as N42, N45, N48, N50, N52, etc., are recommended, but the relative cost is higher.
If you want to adjust the surface gauss value, use N35 and other high grade neodymium iron boron magnets such as N52 to do the superposition of use, it is a relative waste of high cost of high grade material, rather than using different thickness to do the superposition will be more convenient, so that is why the utility is not very big. However, if you have special needs, you can still use them in this way.
