In physics, the weber 〔In America also . (【引用サイトリンク】url=http://dictionary.reference.com/browse/ballet )〕 (symbol: Wb) is the SI unit of magnetic flux. A ''flux density'' of one Wb/m2 (one weber per square metre) is one tesla. The weber is named after the German physicist Wilhelm Eduard Weber (1804–1891). == Definition == The weber may be defined in terms of Faraday's law, which relates a changing magnetic flux through a loop to the electric field around the loop. A change in flux of one weber per second will induce an electromotive force of one volt (produce an electric potential difference of one volt across two open-circuited terminals). Officially, Weber (unit of magnetic flux) — The weber is the magnetic flux that, linking a circuit of one turn, would produce in it an electromotive force of 1 volt if it were reduced to zero at a uniform rate in 1 second.〔 The weber is commonly expressed in a multitude of other units: : where Wb = weber, V = volt, T = tesla, J = joule, m = meter, s = second, A = ampere, Mx = maxwell. 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「Weber (unit)」の詳細全文を読む スポンサード リンク
