 for Magnetic fluid
From The Collaborative International Dictionary of English v.0.48 :

  Fluid \Flu"id\, n.
     A fluid substance; a body whose particles move easily among
     themselves.
     [1913 Webster]
  
     Note: Fluid is a generic term, including liquids and gases as
           species. Water, air, and steam are fluids. By analogy,
           the term was sometimes applied to electricity and
           magnetism, as in phrases electric fluid, magnetic
           fluid, though not strictly appropriate; such usage has
           disappeared.
           [1913 Webster +PJC]
  
     Fluid dram, or Fluid drachm, a measure of capacity equal
        to one eighth of a fluid ounce.
  
     Fluid ounce.
     (a) In the United States, a measure of capacity, in
         apothecaries' or wine measure, equal to one sixteenth of
         a pint or 29.57 cubic centimeters. This, for water, is
         about 1.04158 ounces avoirdupois, or 455.6 grains.
     (b) In England, a measure of capacity equal to the twentieth
         part of an imperial pint. For water, this is the weight
         of the avoirdupois ounce, or 437.5 grains.
  
     Fluids of the body. (Physiol.) The circulating blood and
        lymph, the chyle, the gastric, pancreatic, and intestinal
        juices, the saliva, bile, urine, aqueous humor, and muscle
        serum are the more important fluids of the body. The
        tissues themselves contain a large amount of combined
        water, so much, that an entire human body dried in vacuo
        with a very moderate degree of heat gives about 66 per
        cent of water.
  
     Burning fluid, Elastic fluid, Electric fluid, Magnetic
     fluid, etc. See under Burning, Elastic, etc.

  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.
        [1913 Webster]
  
     2. Of or pertaining to, or characterized by, the earth's
        magnetism; as, the magnetic north; the magnetic meridian.
        [1913 Webster]
  
     3. Capable of becoming a magnet; susceptible to magnetism;
        as, the magnetic metals.
        [1913 Webster]
  
     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.
        [1913 Webster]
  
     5. Having, susceptible to, or induced by, animal magnetism,
        so called; hypnotic; as, a magnetic sleep. See
        Magnetism. [Archaic]
        [1913 Webster +PJC]
  
     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.
        [1913 Webster + PJC]
