or becoming magnetic.
(b) (Physics) In respect to terrestrial magnetism, the
declination, inclination, and intensity.
(c) See under Element.

formerly assumed in the explanations of the phenomena of
magnetism; -- no longer considered a meaningful concept.
Magnetic iron, or Magnetic iron ore. (Min.) Same as
Magnetite.
Magnetic needle, a slender bar of steel, magnetized and
suspended at its center on a sharp-pointed pivot, or by a
delicate fiber, so that it may take freely the direction
of the magnetic meridian. It constitutes the essential
part of a compass, such as the mariner's and the
surveyor's.
Magnetic poles, the two points in the opposite polar

Magnetic storm (Terrestrial Physics), a disturbance of the
earth's magnetic force characterized by great and sudden

magnetic tape (Electronics), a ribbon of plastic material
to which is affixed a thin layer of powder of a material
which can be magnetized, such as ferrite. Such tapes are
used in various electronic devices to record fluctuating
voltages, which can be used to represent sounds, images,
or binary data. Devices such as audio casette recorders,
videocasette recorders, and computer data storage devices
use magnetic tape as an inexpensive medium to store data.
Different magnetically susceptible materials are used in
such tapes.
Magnetic telegraph, a telegraph acting by means of a
magnet. See Telegraph.

Periodic table of the elements
(gcide) | Periodic \Pe`ri*od"ic\ (p[=e]`r[i^]*[o^]d"[i^]k), Periodical
\Pe`ri*od"ic*al\ (p[=e]`r[i^]*[o^]d"[i^]*kal), a. [L.
periodicus, Gr. periodiko`s: cf. F. p['e]riodique.]
1. Of or pertaining to a period or periods, or to division by
periods.
[1913 Webster]
The periodical times of all the satellites. --Sir J.
Herschel.
[1913 Webster]
2. Performed in a period, or regular revolution; proceeding
in a series of successive circuits; as, the periodical
motion of the planets round the sun.
[1913 Webster]
3. Happening, by revolution, at a stated time; returning
regularly, after a certain period of time.
[1913 Webster]
The periodic return of a plant's flowering.
--Henslow.
[1913 Webster]
To influence opinion through the periodical press.
--Courthope.
[1913 Webster]
4. Acting, happening, or appearing, at fixed or somewhat
variable intervals; recurring; as, periodical epidemics
[1913 Webster]
5. (Rhet.) Of or pertaining to a period; constituting a
complete sentence.
[1913 Webster]
Periodic comet (Astron.), a comet that moves about the sun
in an elliptic orbit; a comet that has been seen at two of
its approaches to the sun.
Periodic function (Math.), a function whose values recur at
fixed intervals as the variable uniformly increases. The
trigonomertic functions, as sin(x), tan(x), etc., are
periodic functions. Exponential functions are also
periodic, having an imaginary period, and the elliptic
functions have not only a real but an imaginary period,
and are hence called doubly periodic.
Periodic law (Chem.), the generalization that the
properties of the chemical elements are periodic functions
of their atomic weights. "In other words, if the elements
are grouped in the order of their atomic weights, it will
be found that nearly the same properties recur
periodically throughout the entire series." The following
tabular arrangement of the atomic weights shows the
regular recurrence of groups (under I., II., III., IV.,
etc.), each consisting of members of the same natural
family. The gaps in the table indicate the probable
existence of unknown elements.
Periodic table, Periodic table of the elements (Chem.), A
tabular arrangement of the chemical elements, illustrating
the periodic law, described above.
[1913 Webster]

Note: A similar relation had been enunciated in a crude way
by Newlands; but the law in its effective form was
developed and elaborated by Mendelejeff, whence it is
sometimes called Mendelejeff's law. Important
extensions of it were also made by L. Meyer. By this
means Mendelejeff predicted with remarkable accuracy
the hypothetical elements ekaboron, ekaluminium, and
ekasilicon, afterwards discovered and named
respectively scandium, gallium, and germanium.
[1913 Webster]
Periodic star (Astron.), a variable star whose changes of
brightness recur at fixed periods.
Periodic time of a heavenly body (Astron.), the time of a
complete revolution of the body about the sun, or of a
satellite about its primary.
