Diamagnetism Physics Britannica

The diamagnetism of some materials however is masked either by aweak magnetic attractionparamagnetism or a very strong attraction ferromagnetism diamagnetism is observable in substances with symmetric electronic structure as ionic crystals and rare gases and no permanent magnetic moment diamagnetism is not affected by changes in temperature

Diamagnetic Material An Overview Sciencedirect Topics

Diamagneticmaterialshave no netmagneticmoment without the presence of an external appliedmagneticfield hhowever as an externalmagneticfield is applied to a diamagneticmaterial the spinning electrons experience a motion known as processing producing electrical current and thus a magnetization m which is in the opposite direction to that of the externalmagneticfield as
