  • adjective Of or relating to a substance that generates a magnetic field in the direction opposite to an externally applied magnetic field and is therefore repelled by it.

from The Century Dictionary.

  • Pertaining to or exhibiting diamagnetism.
  • noun A substance which is diamagnetic in a magnetic field of force. See diamagnetism, 1.

  • adjective 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.
  • adjective See under Attraction.
  • noun 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.
