Simple Testing Methods to Identify Magnet Strength
Testing is one of the most effective ways to distinguish a strong magnet from an ordinary one. A high performance magnet, like a neodymium magnet, will attract and hold heavy metal objects despite its small size. In contrast, ordinary magnets will only hold lightweight items and lose magnetism faster over time. Rare earth permanent magnets retain their force for years and do not demagnetize easily. Try using a coin or screwdriver for testing: the stronger the pull, the more likely it is a rare earth permanent magnet. This testing method is widely used in manufacturing, quality inspection, and scientific research to confirm the magnet’s class.
