a diamagnetic material has no unpaired spins; when such a material without permanent dipoles has a magnetic field applied to it, the magnetic dipoles induced in the material line up opposite to that of the induced field
a substance that will slightly decrease a magnetic field when placed within it (its magnetization is oppositely directed to the magnetic field, i e with a small negative magnetic susceptibility)
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
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
