Paramagnetism is a physical property observed in certain materials that are weakly attracted by an external magnetic field. This attraction occurs because these materials have unpaired electrons in their atomic or molecular structure. When exposed to a strong magnetic field, the magnetic moments of these unpaired electrons tend to align with the field, causing a net attraction. However, paramagnetic materials do not retain magnetic properties once the external field is removed, unlike ferromagnetic materials. In cybersecurity, understanding paramagnetism is relevant in the context of hardware security, such as the design and shielding of electronic components that may be affected by magnetic fields.
