|ferromagnetism Compare paramagnetism 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|
diamagnetism [%PREMIUM_LINK%] (dī'ə-māg'nĭ-tĭz'əm) Pronunciation Key |
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. Compare ferromagnetism, paramagnetism. See also Lenz's law.
