Faraday's law of induction - Wikipedia
The most widespread version of Faraday's law states:
The electromotive force around a closed path is equal to the negative of the time rate of change of the magnetic flux enclosed by the path.
For a loop of wire in a magnetic field, the magnetic flux ΦB is defined for any surface Σ whose boundary is the given loop. Since the wire loop may be moving…Wikipedia · CC-BY-SA ライセンス について表示されるテキスト- 推定読み取り時間:9 分
