electromagnetism    音标拼音: [ɪl,ɛktrom'ægnət,ɪzəm]
n. 电磁,电磁学

电磁,电磁学

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 [synonym: {electromagnetism}, {electromagnetics}]

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]
