measured by the angle which it subtends at the eye of the
observer; -- called also apparent diameter.
2. (Astron.) Same as magnitude of a star, below.
Magnitude of a star (Astron.), the rank of a star with
respect to brightness. About twenty very bright stars are
said to be of first magnitude, the stars of the sixth
magnitude being just visible to the naked eye; called also
visual magnitude, apparent magnitude, and simply
magnitude. Stars observable only in the telescope are
classified down to below the twelfth magnitude. The
difference in actual brightness between magnitudes is now
specified as a factor of 2.512, i.e. the difference in
brightness is 100 for stars differing by five magnitudes.

increased. See Brilliant, Rose. Diamonds are said
to be of the first water when very transparent, and of

diamagnetic
(gcide) | Attraction \At*trac"tion\, n. [L. attractio: cf. F. attraction.]
1. (Physics) An invisible power in a body by which it draws

between bodies or ultimate particles, tending to draw them
together, or to produce their cohesion or combination, and

Note: Attraction is exerted at both sensible and insensible
distances, and is variously denominated according to
its qualities or phenomena. Under attraction at
sensible distances, there are, -- (1.)
Attraction of gravitation, which acts at all distances
throughout the universe, with a force proportional
directly to the product of the masses of the bodies and
inversely to the square of their distances apart. (2.)
Magnetic, diamagnetic, and electrical attraction, each
of which is limited in its sensible range and is polar in
its action, a property dependent on the quality or
condition of matter, and not on its quantity. Under
attraction at insensible distances, there are, -- (1.)
Adhesive attraction, attraction between surfaces of
sensible extent, or by the medium of an intervening
substance. (2.)
Cohesive attraction, attraction between ultimate particles,
whether like or unlike, and causing simply an aggregation

gases by charcoal, or of oxygen by spongy platinum, or the
process of solidification or crystallization. The power in
adhesive attraction is strictly the same as that of
cohesion. (3.)
Capillary attraction, attraction causing a liquid to rise,
in capillary tubes or interstices, above its level
outside, as in very small glass tubes, or a sponge, or any
porous substance, when one end is inserted in the liquid.

Chemical attraction, or
affinity, that peculiar force which causes elementary
atoms, or groups of atoms, to unite to form molecules.

2. The act or property of attracting; the effect of the power
or operation of attraction. --Newton.

3. The power or act of alluring, drawing to, inviting, or
engaging; an attractive quality; as, the attraction of
beauty or eloquence.
[1913 Webster]
4. That which attracts; an attractive object or feature.

Syn: Allurement; enticement; charm.
[1913 Webster]Diamagnetic \Di`a*mag*net"ic\, 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.
Contrasted with paramagnetic and ferromagnetic.
[1913 Webster]Diamagnetic \Di`a*mag*net"ic\, a.

diameter of its pitch circle in inches; as, 4 pitch, 8
pitch, etc.

Pitch line, or Pitch circle (Gearing), an ideal line, in
a toothed gear or rack, bearing such a relation to a
corresponding line in another gear, with which the former
works, that the two lines will have a common velocity as
in rolling contact; it usually cuts the teeth at about the
middle of their height, and, in a circular gear, is a
circle concentric with the axis of the gear; the line, or
circle, on which the pitch of teeth is measured.
Pitch of a roof (Arch.), the inclination or slope of the
sides expressed by the height in parts of the span; as,
