  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. 
 
  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}.
