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.
4. Endowed with extraordinary personal power to excite the
feelings and to win the affections; attractive; inducing
attachment.
She that had all magnetic force alone. --Donne.
5. Having, susceptible to, or induced by, animal magnetism,
so called; as, a magnetic sleep. See {Magnetism}.
{Magnetic amplitude}, {attraction}, {dip}, {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 {Element}.
{Magnetic equator}, the 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 magnet exerts its influence.
{Magnetic fluid}, the hypothetical fluid whose 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 telegraph acting by means of a
magnet. See {Telegraph}.
