diamagnetic in Science
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.
