From The Collaborative International Dictionary of English v.0.48 :

  Electro-magnetism \E*lec`tro-mag"net*ism\ n.
     1. magnetism produced by an electric current.
        [WordNet 1.5]
  
     2. one of the fundamental forces of nature, responsible for
        both electrical and magnetic phenomena. Called also the
        electromagnetic force. Formerly believed to be separate
        phenomena, electricity and magnetism were shown by
        experiment and theory to be different aspects of the
        electromagnetic force. It is responsible for the forces
        generated between magnetically or electrically charged
        objects, and is the fundamental force responsible for the
        characteristics of electromagnetic radiation, including
        light.
        [PJC]
  
     3. the branch of physics concerned with electromagnetic
        phenomena.
        [WordNet 1.5]

From WordNet (r) 3.0 (2006) :

  electromagnetism
      n 1: magnetism produced by an electric current;
           "electromagnetism was discovered when it was observed that
           a copper wire carrying an electric current can magnetize
           pieces of iron or steel near it"
      2: the branch of physics concerned with electromagnetic
         phenomena [syn: electromagnetism, electromagnetics]
