Paramagnets are materials that are weakly attracted to magnetic fields. This property arises from the presence of unpaired electrons in their atomic structure, which create tiny magnetic moments. When exposed to an external magnetic field, these moments tend to align with the field, but the effect is temporary and disappears once the field is removed. Unlike ferromagnets, which retain their magnetism, paramagnets do not hold any magnetization in the absence of an external field. Common examples of paramagnetic materials include aluminum, manganese, and certain metal ions. Their behavior is important in various applications, including magnetic resonance imaging (MRI).
