1. Verify Material AuthenticityCheck the grade certification provided by the supplier. Genuine N52 neodymium magnets should come with a test report specifying magnetic energy product (BHmax) ≥ 52 MGOe, coercivity, and residual magnetism.2. Choose Reputable SuppliersOpt for manufacturers or distribut

1. Check Magnetic StrengthUse a pull force tester to measure the attraction force; high-quality magnets offer stable, strong pull force matching the labeled grade.2. Inspect Surface & CoatingPremium magnets have smooth surfaces without scratches, chips or rust. The coating (Ni-Cu-Ni, epoxy, etc.) sh

Rare earth permanent magnets (e.g. neodymium-iron-boron, samarium-cobalt) are significantly more expensive than ordinary magnets such as ferrites. The core reasons lie in scarce resources, sophisticated production processes, performance premium, and the combined effects of policies, supply and deman

How to Judge Whether a Magnet Has Demagnetized?There are two ways to judge whether a magnet has demagnetized: simple detection and professional instrument testing, which are suitable for different scenarios:1. Simple Detection Method (On-site Quick Judgment)◦ Adsorption Force Comparison: Use the ma

The Quick Magnet Buying Guide: Pick the Right One for Your ProjectMagnets are critical to countless industries—but choosing the wrong type costs time and money. Here’s how to select the perfect magnet in 3 simple steps:1. Choose the Right Magnet Type◦ Neodymium (NdFeB): Strongest, best for EV moto

In fact, the motor route without rare earths has always existed, but because the performance is not as good as that of rare earth permanent magnets, there is no technological subversion. The wrong killing of the rare earth sector also brings opportunities, and we can pay attention to the better link

Supply security is crucial, and the rare earth industry chain is getting healthier. Safe procurement of rare earths is a very critical part of the current strategic development of various countries. As a country with the most concentrated rare earth resources and the most advanced mining technology,

NdFeB magnets are known for their superior magnetic strength. They are a rare earth magnet, made from an alloy of neodymium. Although there are other types of rare earth magnets, such as samarium cobalt magnets, neodymium iron boron magnets are the most powerful permanent magnets in commercial use a
