  From  Webster's  Revised  Unabridged  Dictionary  (1913)  [web1913]: 
 
  Solenoid  \So"len*oid\,  n.[Gr.  ???  channel  +  -oid.]  (Elec.) 
  An  electrodynamic  spiral  having  the  conjuctive  wire  turned 
  back  along  its  axis,  so  as  to  neutralize  that  component  of 
  the  effect  of  the  current  which  is  due  to  the  length  of  the 
  spiral,  and  reduce  the  whole  effect  to  that  of  a  series  of 
  equal  and  parallel  circular  currents.  When  traversed  by  a 
  current  the  solenoid  exhibits  polarity  and  attraction  or 
  repulsion,  like  a  magnet.

  n  :  a  coil  of  wire  around  an  iron  core;  becomes  a  magnet  when 
  current  passes  through  the  coil
