So does the induced current run from "- to +" or "+ to -" in the coil? It is my understanding that it is the latter (since I was led to believe that current's direction is that of a positive charge carrier), which is why I'm having trouble understanding...

One thing that I still don't undestand is how does the "Lenz's law emf" interact with the coil? It's my understanding that this is a "battery" that is connected to the corresponding ends of the coil and producing a "counter-current" through the coil. And this current is from + to - as I...

I have a conceptual question regarding the self-induced emf in a solenoid coil. I have attached a graphic from Serway's Physics for Scientists and Engineers (6th edition) from Chapter 32 (Inductance). My question is regarding induced emf's (called "Lenz's law emf" in figures (b) and (c)) in...
