Relationship between magnetic strength and Gauss of magnet

What is the relationship between the magnetic strength of a magnet and gauss?This problem found that a lot of people are more concerned, today this problem with you a brief introduction.

First of all, remember this sentence: the higher the Gauss of a magnet of the same size, the greater the magnetism. For magnets of different specifications, the larger the Gauss is, the stronger the magnetic force is not necessarily, The reason is that the surface magnetism of magnet is related to the ratio of height to diameter of magnet (the ratio of height to diameter of magnet). The larger the ratio of height to diameter is, the higher the surface magnetism is. That is to say, the larger the surface area based on the magnetization direction is, the lower the surface magnetism is. The smaller the surface area based on the magnetization direction is, the larger the surface magnetism is, and the inverse ratio is formed. The thicker the magnetization direction is, the higher the surface magnetism is. The smaller the magnetization direction, the lower the surface magnetism.

I'm sure a lot of people don't understand it. Here are a few examples.

For example, NdFeB columnar D8 * 10, surface magnet 5000 Gauss, NdFeB d30 * 10, surface magnet 3087gs, obviously, the surface magnet with larger diameter is lower, but the magnetic force is naturally strong in d30 * 10, so the magnetic strength of magnet is related to the volume (contact surface) of magnet.

In addition, the magnetic size of the magnet is also related to the intrinsic coercive force, Generally, the product of H and B is used to reflect the magnetic strength of the magnet. The large value of B indicates that some points on the surface of the magnet are more magnetic.


Conclusion: through the introduction of this paper, we know that the magnetic strength of magnet can not be judged according to Gauss. The magnetic strength of magnet is related to material (n35-n52), manufacturing process, volume, service temperature and magnetization direction.
