PARAMAGNETS Meaning and
Definition
-
Paramagnets, in the field of physics, refer to materials that possess weak magnetism when exposed to an external magnetic field, but lose their magnetism once the field is removed. These materials are characterized by unpaired electrons in their atomic or molecular structure, which gives them the ability to align their magnetic moments with the applied field. The alignment of these moments causes the material to become magnetized temporarily. However, unlike ferromagnetic materials, which retain their magnetization even after the field is withdrawn, paramagnets return to their non-magnetic state.
Paramagnetic materials exhibit a response to magnetism that is proportional to the strength of the applied field, but they do not possess permanent magnetic dipoles. This means that their magnetic susceptibility is positive, but very small. It is the weak interaction between the magnetic moments of paramagnetic substances that prevents the attainment of a permanent magnetized state.
Examples of paramagnetic materials include aluminum, platinum, oxygen, and lithium. They are often used in various applications such as magnetic resonance imaging (MRI), where their temporary magnetization in the presence of a strong magnetic field helps in generating clear and detailed images of the internal body structures.
In summary, paramagnets are materials that exhibit weak, temporary magnetism when subjected to an external magnetic field due to the alignment of unpaired electrons. However, their lack of permanent magnetic dipoles makes them lose magnetization once the field is removed.

Etymology of PARAMAGNETS
The word "paramagnets" is derived from the combination of two terms: "para" and "magnets".
1. "Para": The term "para" is derived from the Greek word "παρά" (para), which means "beside" or "beyond". In scientific terminology, the prefix "para-" often denotes something that is similar but not identical to the main term. It implies a parallel or analogous nature.
2. "Magnets": The word "magnets" originates from the Latin term "magnes" or "magnesia", which referred to a type of iron ore found in Magnesia, a region in Thessaly, Greece. This ore was known to possess magnetic properties and was used in compasses.
