noun

1. the phenomenon exhibited by substances that have a relative permeability less than unity and a negative susceptibility. It is caused by the orbital motion of electrons in the atoms of the material and is unaffected by temperature Compare ferromagnetism paramagnetism

diamagnetism Scientific  

/ dī′ə-măg′nĭ-tĭz′əm /

1. The property of being repelled by both poles of a magnet. Most substances commonly considered to be nonmagnetic, such as water, are actually diamagnetic. Though diamagnetism is a very weak effect compared with ferromagnetism and paramagnetism, it can be used to levitate objects.

2. Compare ferromagnetism paramagnetism See also Lenz's law

Example Sentences

Although other types of magnetism, such as diamagnetism and paramagnetism have been categorised, these describe specific responses to externally applied magnetic fields rather than spontaneous magnetic orderings in materials.
