How should NdFeB magnets be stored?

Store in a dry, cool place away from heat sources, other magnets, and electronic devices. Handle carefully to avoid cracking as they are brittle.

How do you compare magnet quality?

Quality is determined by raw material purity, manufacturing process, and post-processing. High-quality magnets have low impurities and defects, ensuring good performance.
