What are the differences between the different sizes of magnets produced by a batch of permanent magnet materials?

When we produce strong magnets, we often encounter some customer questions, that is, customers found the magnetic force of different sizes of magnets is different, even though they are produced by a batch of material. In this case, we magnet manufacturers will explain to customers, magnets, its magnetic force is mainly depended on Gauss value. This Gauss value is the one our permanent magnet manufacturers often say the magnetic unit. Usually the larger value of this Gauss value, the stronger the magnetic force, then why the different dimensions produced, its Gaussian value is not the same? Let me talk about this question today.

The composition of the powerful magnet is made of NdFeB permanent magnetic material, in the theoretical data, if we use the same material under the same condition, while the magnet thickness decreases, the Gauss value of the magnet will also decrease, and then the magnetic force becomes weaker. The magnetism will increase with the increase of the area.

Here is one key point I would like to mention. The higher the surface Gauss value of magnets indicates the greater the magnetic force per unit area! Magnetic force = unit area of surface Gauss value* per unit area. However, it can’t jump to the conclusion that the magnetic force must be large with high surface Gauss value.

Therefore, permanent magnets in the same batch of materials produced by different sizes of magnets will have a Gauss value difference, which is actually a normal phenomenon. If you still have the other relevant questions of magnets, please feel free to contact us.
