学习法拉第电磁感应定律时,应注意公式E=n(ΔΦ/Δt)与E=BLvsinθ的区别和联系。(1)E=n(ΔΦ/Δt)求出的是Δt时间内的平均感应电动势,E与某段时间或某个过程相对应
When studying Faraday's law of electromagnetic induction, pay attention to the difference and relation between E = n (ΔΦ / Δt) and E = BLvsinθ. (1) E = n (ΔΦ / Δt) Find the average induced electromotive force in Δt, E corresponds to a period of time or a certain process
