Science definitions for diamagnetism

diamagnetism

[ dī′ə-măg′nĭ-tĭz′əm ]

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.
