[QUOTE="Einstein44, post: 6516718, member: 692278"] [B]Homework Statement:[/B] When studying Lenzs Law / Faradays Law, I came across two different types of equations and do not know which one is correct. What I need to find is the induced voltage on a copper coil, as a magnet moves through it. Can someone help tell me which one is appropriate to use in this case? [B]Relevant Equations:[/B] 1. E= - ∂ΦB/∂t where ΦB= rate of change in magnetic flux E= induced voltage 2. E = -N x Δø/Δt where N= number of turns in the coil Δø = change in flux inside the coil As you can notice the second equation takes into account the number of turns in the coil, whereas the other equation doesn't despite being also used for a coil. And what is even the difference between having a partial derivative in the equation and instead "delta" for change in magnetic flux over change in time?? . [/QUOTE]
