Diamagnetic: meaning, definitions and examples
🧲
diamagnetic
[ ˈdaɪəˈmæɡnɪk ]
magnetism property
Diamagnetic refers to a property of materials that are repelled by magnetic fields. This occurs due to the material's electron configuration, where the electrons do not have any unpaired spins, leading to a weak repulsion in the presence of a magnetic field.
Synonyms
Examples of usage
- Bismuth is a diamagnetic metal.
- The diamagnetic properties of graphite are notable.
- Diamagnetic materials have no net magnetic moment.
Word origin
The term 'diamagnetic' originates from the Greek word 'dia', meaning 'through' or 'across', and 'magnet', derived from the Latin word 'magnes', meaning 'magnet'. The 19th-century physicist Michael Faraday's studies on magnetic forces in materials led to the identification of diamagnetic properties. He used the term to describe materials that are weakly repelled by magnetic fields. The notion of diamagnetism developed further with the understanding of atomic theory, highlighting how electron arrangements influence magnetic behaviors. Since then, the term has been integral to the study of material sciences and electromagnetism, reflecting the fascinating interplay between magnetic fields and matter.
