Can Copper Be Magnetised Pure copper cannot be permanently magnetized because it is a diamagnetic material with paired electrons that repel magnetic fields. Copper is different from iron or nickel because it doesn’t have the atomic structure needed for ferromagnetism or permanent magnetism. Let me clear something up right away. If you’re picturing a copper [...]
