{ Mag*net"ic (?), Mag*net"ic*al (?), }
a. [L. magneticus: cf. F.
magnétique.] 1. Pertaining to the

needle.
2. Of or pertaining to, or characterized by,
the earth's magnetism; as, the magnetic north; the
magnetic meridian.
3. Capable of becoming a magnet; susceptible
to magnetism; as, the magnetic metals.

induction, etc. See under Amplitude,
Attraction, etc. -- Magnetic battery,
a combination of bar or horseshoe magnets with the like poles
adjacent, so as to act together with great power. --
Magnetic compensator, a contrivance connected
with a ship's compass for compensating or neutralizing the effect of
the iron of the ship upon the needle. -- Magnetic
curves, curves indicating lines of magnetic force, as
in the arrangement of iron filings between the poles of a powerful
magnet. -- Magnetic elements.
(a) (Chem. Physics) Those elements, as
iron, nickel, cobalt, chromium, manganese, etc., which are capable or
becoming magnetic. (b) (Physics) In
respect to terrestrial magnetism, the declination, inclination, and
intensity. (c) See under

line around the equatorial parts of the earth at which there is no
dip, the dipping needle being horizontal. -- Magnetic
field, or Field of magnetic force,
any space through which a magnet exerts its influence. --

existence was formerly assumed in the explanations of the phenomena
of magnetism. -- 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 regions of the earth at which the
direction of the dipping needle is vertical. -- Magnetic
pyrites. See Pyrrhotite. --
Magnetic storm (Terrestrial Physics), a
disturbance of the earth's magnetic force characterized by great and
sudden changes. -- Magnetic telegraph, a
