# diamagnetic

## Definitions

• WordNet 3.6
• adj diamagnetic relating to or exhibiting diamagnetism; slightly repelled by a magnet
• ***
Webster's Revised Unabridged Dictionary
• n Diamagnetic Any substance, as bismuth, glass, phosphorous, etc., which in a field of magnetic force is differently affected from the ordinary magnetic bodies, as iron; that is, which tends to take a position at right angles to the lines of magnetic force, and is repelled by either pole of the magnet. Contrasted with paramagnetic and ferromagnetic.
• a Diamagnetic Pertaining to, or exhibiting the phenomena of, diamagnetism; taking, or being of a nature to take, a position at right angles to the lines of magnetic force. See Paramagnetic.

Chambers's Twentieth Century Dictionary
• adj Diamagnetic dī-a-mag-net′ik cross-magnetic—applied to any substance, such as a rod of bismuth or glass, which, when suspended between the poles of a magnet, arranges itself across the line joining the poles (a rod of iron or of sealing-wax so held arranges itself parallel to the line joining the poles, and is said to be Paramagnetic)
