What are the differences between magnets of different sizes produced from the same batch of magnet materials?
When we produce powerful magnets, we often encounter some questions from customers, that is, different sizes of magnets produced by customers with the same magnet material have different magnetic forces. In this case, our magnet manufacturers will explain to customers that the magnetic force of a magnet is mainly represented by Gauss value, which is the unit of magnetic force that our magnet manufacturers often say. Generally, the larger the Gauss value is, the stronger the magnetic force is. So why are the Gauss values of different sizes produced different? Let’s talk about this today.
The strong magnet is composed of NdFeB material. According to the theoretical data, when the same material is equal, the thickness of the magnet decreases, the Gauss value of the magnet decreases, and then the magnetic force becomes weak. The magnetic force of the magnet will increase with the increase of the area.
The higher the surface magnetism of the magnet, the greater the suction per unit area. Suction = unit surface magnetism * unit area. However, we can’t simply think that the magnetic attraction of high surface magnetism must be large!
So to sum up, different sizes of magnets produced from the same batch of materials will have different Gauss values. This is actually a normal phenomenon. If you have any questions about magnets, please contact us.
