Is copper a ferromagnetic material?

No, copper is not a ferromagnetic material. Ferromagnetism is a property exhibited by certain materials, such as iron, nickel, and cobalt, where they can become strongly magnetized when placed in a magnetic field and retain that magnetization even after the magnetic field is removed.

Copper, on the other hand, is a non-ferromagnetic material. It is classified as a diamagnetic material, which means it weakly repels a magnetic field and does not retain any magnetization when the external magnetic field is removed. Copper's diamagnetic properties are a result of the electrons in its atoms responding to the applied magnetic field in a way that opposes the field, causing a very weak repulsion.
