Method for testing the quality of powerful magnets
Powerful magnets have better performance and quality than ferrites. Powerful neodymium magnets can absorb 640 times more weight than their own, which is why they are awarded the title of "Magnetic King".
I don’t know the quality of the powerful magnets on the market. Don’t let others know that you are a layman. Is there a quality inspection method to quickly detect strong neodymium magnets?
Testing the quality of the strong NdFeB magnet is mainly evaluated from two aspects: 1. Product performance; 2. Product appearance.
One, product performance:
The strength of neodymium magnets is a unified standard. The main indicators are remanence, coercivity and magnetic energy product grade. Strong neodymium magnets of different sizes can be distinguished by Gaussian sum. The quality and performance of this magnet can be distinguished by Gaussian, coercive force It can only pass the magnetic performance tester, and the general user cannot test it.

2. Product appearance:
You can pick it up to check the appearance of the product, mainly looking at the five aspects of the appearance:
(1) Pitting corrosion: including bubbles. Scars, plating tumors, slag layer and local thickness;
(2) Edge crack: edge crack and material residue;
(3) Scratches: knife marks, line marks, nail scratches, etc.
(4) Cracks: cracks and so on.
(5) Sand holes: pinholes, pores, particles, etc., depending on whether there are missing edges or corners around, whether the electroplating is intact, and whether the size meets the design requirements. Neodymium magnet coating prevents corrosion and rust on the surface of the magnet. The same specification is placed on a surface that can be adsorbed, which can be used to distinguish the magnitude of the magnetic force.
If you compare the user's requirements for strong magnets, you can understand the magnetic properties of the measured magnet through the demagnetization curve classification analysis.
The above is the quality inspection method of powerful neodymium magnets, hope to help you how to quickly identify the quality of powerful magnets.

View detailsWhat is the difference between a strong magnet and an ordinary magnet?
Speaking of magnets, we are familiar with them when we return home. They can attract iron, but magnets are not invented by humans. They are natural magnetite. The ancient Greeks and Chinese found natural magnetized stones in nature, which can attract small pieces of iron. Early navigators used magnets as compasses to identify the direction of the sea. Magnets as a compass were also one of China's four great inventions. With the development of society, various magnets have been discovered. Let's introduce the difference between powerful magnets and different magnets.
View detailsWhat should I pay attention to when customizing spherical magnets?
Spherical magnet customization is not uncommon for our magnet manufacturers. It is an ordinary spherical product with special application fields. Spherical magnets are not used in all industries. Take the spherical magnets we produce as an example. They are mostly used in mechanical equipment. Magnets have a characteristic and are very sensitive to magnetic fields. When there is current, there is a magnetic field. If there is a magnetic field, the magnet ball will sway, so that the current safety on the mechanical equipment can be guaranteed.
