翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Electric field ： ウィキペディア英語版 Electric field The electric field is a component of the electromagnetic field. It is a vector field and is generated by electric charges or time-varying magnetic fields, as described by Maxwell's equations. The concept of an electric field was introduced by Michael Faraday.〔http://public.wsu.edu/~jtd/Physics206/michael_faraday.htm〕 ==Definition== The electric field $\backslash mathbf$ at a given point is defined as the (vectorial) force $\backslash mathbf$ that would be exerted on a stationary test particle of unit charge by electromagnetic forces (i.e. the Lorentz force). A particle of charge $q$ would be subject to a force $\backslash mathbf=q\backslash cdot\backslash mathbf$. Its SI units are newtons per coulomb (N⋅C−1) or, equivalently, volts per metre (V⋅m−1), which in terms of SI base units are kg⋅m⋅s−3⋅A−1. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Electric field」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
