Copper is a paramagnetic material, meaning it weakly interacts with magnetic fields. This property arises from the presence of unpaired electrons in the outermost electron shell of copper atoms. Quantum mechanics governs the behavior of these unpaired electrons, resulting in a net magnetic moment. The magnetic moments of individual copper atoms align slightly with an external magnetic field, producing a weak but measurable magnetic response.
