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]
