nonmagnetized

A substance is described as nonmagnetized if it does not exhibit magnetic properties. This means it does not generate its own magnetic field and does not respond to external magnetic fields in a way that would cause attraction or repulsion. Materials that are nonmagnetic are generally not composed of atoms with unpaired electrons, which are typically responsible for magnetic behavior. Examples of nonmagnetized materials include most plastics, wood, aluminum, and copper under normal conditions. These materials do not become permanently magnetized when placed in a magnetic field. While some substances can be temporarily magnetized, they revert to a nonmagnetized state once the external field is removed. The term is often used in contrast to magnetized materials, such as ferromagnetic substances, which can retain their magnetic properties after being exposed to a magnetic field. Understanding whether a material is magnetized or nonmagnetized is important in various scientific and engineering applications, particularly where magnetic interference needs to be avoided or where magnetic fields are intentionally employed.
