\Mag*net"ic\, Magnetical \Mag*net"ic*al\, a. [L.
magneticus: cf. F. magn['e]tique.]
1. Pertaining to the magnet; possessing the properties of the
   magnet, or corresponding properties; as, a magnetic bar of
   iron; a magnetic 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.
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}.

\Mag*net"ic\, n.
1. A magnet. [Obs.]
         As the magnetic hardest iron draws.   --Milton.
2. Any metal, as iron, nickel, cobalt, etc., which may
   receive, by any means, the properties of the loadstone,
   and which then, when suspended, fixes itself in the
   direction of a magnetic meridian.
