I was reading electromagnetic induction and came across EMF.Now in my text book as the theory has been developed ,they have many a times talked about direction of EMF.
But they have not clearly defined it.When i searched Google,I got this-
Electromotive force, also called emf( measured in volts), is the voltage developed by any source of electrical energy such as a battery or dynamo.
The word "force" in this case is not used to mean mechanical force, measured in newtons, but a potential, or energy per unit of charge, measured in volts.
In electromagnetic induction, emf can be defined around a closed loop as the electromagnetic work that would be transferred to a unit of charge if it travels once around that loop
So if it is actually work done,how come it has a direction?
