diamagnetic – מילון אנגלי-אנגלי
diamagnetic
adj.
of substances whose permeability is less than that of a vacuum (Physics)
Diamagnetism
Diamagnetic materials create an
induced magnetic field in a direction opposite to an externally
applied magnetic field, and are repelled by the applied magnetic field. In contrast, the opposite behavior is exhibited by
paramagnetic materials.
Diamagnetism is a
quantum mechanical effect that occurs in all materials; when it is the only contribution to the magnetism the material is called a
diamagnet. Unlike a
ferromagnet, a diamagnet is not a permanent magnet. Its
magnetic permeability is less than µ
0, the permeability of vacuum. In most materials diamagnetism is a weak effect, but a
superconductor repels the magnetic field entirely, apart from a thin layer at the surface.
diamagnetic
Adjective
1. relating to or exhibiting diamagnetism; slightly repelled by a magnet
(pertainym) diamagnetism
Diamagnetic
(n.)
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.
(a.)
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.

Say it Compare with
paramagnetism .Diamagnetic materials are very weakly repelled by magnetic fields. The atoms or molecules of diamagnetic materials contain no
unpaired spins .
