磁通量是电磁感应中的一个重要物理量,法拉第电磁感应定律E=ΔΦ/Δt中的E是感应电动势的大小,楞次定律是判定感应电流方向的基本定律.考虑到楞次定律,把法拉第电磁感应定律写为
Magnetic flux is an important physical quantity in electromagnetic induction. Faraday’s Law of Electromagnetic Induction E = ΔΦ / Δt E is the magnitude of induced electromotive force, and Lenz’s law is the basic law for determining the direction of induced current.According to Lenz’s Law, the Faraday’s electromagnetic induction Law written as
