设闭合电路是一个n匝线圈,且穿过每匝线圈的磁通量的变化率都相等且均为ΔΦΔt,则法拉第电磁感应定律用公式可表示为:E =nΔΦΔt.一、磁通量的变化仅由于磁场随时间发生变化引起的,则E =nSΔBΔt;若磁通量的变化仅由于磁场随一维空间发生变化引起的,则E =nSΔBΔx·ΔxΔt=nS
Given that the closed circuit is a n-turn coil, and the rate of change of magnetic flux across each coil is equal and both are ΔΦΔt, Faraday’s law of electromagnetic induction can be expressed by the formula: E = nΔΦΔt. I. Magnetic flux changes only due to the magnetic field As a result of changes over time, E = nSΔBΔt; if the magnetic flux changes only due to a change in magnetic field with one-dimensional space, then E = nSΔBΔx · ΔxΔt = nS
