I've always understood voltage as the difference between two plates. The more i think about it, the more i disagree with it. Wouldn't the voltage induced by a magnet in a generator be, well, voltage? There isn't a difference between two plates, its just the magnetic field interacting with the electric fields of the electrons which moves them, which causes a chain reaction right? So if this is correct, could you get an instance of current through a wire if you just touched it to the negative (most electrons) terminal of a battery because the electrons are trying to push away from each other so they would spread out across the newly attached wire to equalize the distance between each other?

lundyjb,

 I've always understood voltage as the difference between two plates.
Difference? What kind of difference?

 Wouldn't the voltage induced by a magnet in a generator be, well, voltage
And what is that?

 There isn't a difference between two plates, its just the magnetic field interacting with the electric fields of the electrons which moves them, ...
There are no magnetic fields when you run a comb through your hair, yet voltage is produced.

 ...which causes a chain reaction, right?
