   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 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 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 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.
