Electromotive Force is often mentioned in Battery (I don't know how it works in battery), but I want to know how it works in electric generator....
I can't find any explanation that that makes me clearly understand it.
How magnetic Induction Works? <-- "When the magnetic flux through the wire changes, as it moves down, Faraday's law of induction says that it acquires an electromotive force."
"The "electromotive force" will now cause a current to flow in the external resistor R. This means that a similar current (electron flow) flows through the rod PQ itself, giving a magnetic force to the left."
So electromotive force is the main thing that makes electrons move (electric current) in one direction?
