Regarding the adsorption force of NdFeB permanent magnets, many customers will ask, how to calculate the adsorption force of neodymium magnets? How to calculate the adsorption force of neodymium magnets? Next, the editor of the powerful magnet will take everyone to learn more about the "adsorption force" of the strong magnet.

#NdFeB magnet#

1. Estimation of adsorption force:

The formula for calculating the adsorption force of general NdFeB magnets: total weight * 600 times = adsorption force (PS: total weight = volume * density)

The formula for calculating the adsorption force of circular NdFeB magnets: volume * density * 600 times = adsorption force Example: 20mm*5mmN35 neodymium magnet Adsorption force = (10 radius * 10 radius * 3.14 * 5 thickness) volume * 0.0075 density * 600 times = 7065g (g) In other words, 20*5 N35 powerful magnets can absorb 7.065 kg of objects.

The formula for calculating the adsorption force of rectangular NdFeB magnets: volume * density * 600 times = adsorption force Example: 20mm*10mm*5mmN35 neodymium magnet Adsorption force = (20 length * 10 width * 5 thickness) * 0.0075 density * 600 = 4500g in other words, 20*10*5 N35 powerful magnets can absorb 4.5 kg of objects.

If our magnet specifications are two specifications and models, which can be estimated with calculation formulas, it should be noted that the size unit is millimeter (mm), and it can be converted into centimeters if necessary. The pulling force calculated by the above method is not an accurate value and can only be used for reference.

2. Three key factors affecting the magnet attraction:

The adsorption force of a neodymium magnet has a certain relationship with its volume, performance grade, and spacing. Volume: the larger the volume, the greater the suction

Performance grade: The larger the grade, the greater the adsorption force. For example, for a powerful magnet of the same size, N52 has a much higher adsorption force than N38.

Distance: refers to the distance between the powerful magnet and the adsorbed object, the smaller the distance, the greater the adsorption force. vice versa.
