Attraction \At*trac"tion\, n. [L. attractio: cf. F. attraction.]

  1. (Physics) An invisible power in a body by which it draws anything to itself; the power in nature acting mutually between bodies or ultimate particles, tending to draw them together, or to produce their cohesion or combination, and conversely resisting separation.

    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 or a union of those particles, as in the absorption of 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. It is a special case of cohesive attraction. (

  4. )

    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.

    3. The power or act of alluring, drawing to, inviting, or engaging; an attractive quality; as, the attraction of beauty or eloquence.

    4. That which attracts; an attractive object or feature.

    Syn: Allurement; enticement; charm.


Magnetic \Mag*net"ic\, n.

  1. A magnet. [Obs.]

    As the magnetic hardest iron draws.

  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.


Magnetic \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.

  5. Having, susceptible to, or induced by, animal magnetism, so called; hypnotic; as, a magnetic sleep. See Magnetism. [Archaic] 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.

    1. (Chem. Physics) Those elements, as iron, nickel, cobalt, chromium, manganese, etc., which are capable or becoming magnetic.

    2. (Physics) In respect to terrestrial magnetism, the declination, inclination, and intensity.

    3. See under Element.

      Magnetic fluid, the hypothetical fluid whose existence was 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 (disambiguation)

Magnetic may refer to:

  • Magnetic field
Magnetic (album)

Magnetic is the tenth studio album by American rock band Goo Goo Dolls, released on June 11, 2013, through Warner Bros. Records. The album is available on CD, Vinyl and as a digital download.

The recording process took place during the latter half of 2012 and into early 2013. Rzeznik thought of the album title during a phone conversation with his manager, who told Rzeznik to "think of a title for the record. Try to use one word." Magnetic was the first word that came to Rzeznik's mind. This is the last album to feature drummer Mike Malinin who left the band in December 2013.
