unmagnetized
Unmagnetized describes a state in which a material has no net magnetic moment or macroscopic magnetization. In practice, it means the material is not in a magnetized state and does not retain a persistent magnetic moment when no external magnetic field is present. This can occur when magnetic domains within a ferromagnetic material are oriented randomly, so their individual moments cancel each other out, or in materials that do not exhibit spontaneous magnetization (such as paramagnets or diamagnets) where any magnetization is only induced by an external field.
In ferromagnetic materials, magnetization arises from aligned magnetic domains. An unmagnetized piece typically has undergone demagnetization
Measurement of magnetization is usually described by the magnetization vector M or the remanent flux density
The term unmagnetized is often used in practical contexts to distinguish objects or samples with negligible
