 >>Ralph -

My physics book gave me yet another meaning for EMF. The book gave units for
EMF as joules per coulomb. >>>>This is definitely electrical energy but the 
word
is EMForce and force is not energy. Could it be the reason that Faraday
never used EMF to describe induction?<<<<<

What's in a name? EMF is a measure of the energy required to separate charges
to establish a seat of electromotive force. That energy is measured in Joules /
Coulomb which causes all the confusion.

 >>>> I have not found that Faraday ever
used EMF in describing his experiments. He used induced, induction, and
"inductive electrical action".

It's interesting that you are researching Faraday' experiments. I doubt that
either Faraday or Henry gave any thought to a "seat of emf" as their 
experiments
established the principles of electromagnetic induction based on a motional
seat of electromotive force. A chemical or an electrostatic (VDG, Wimshurst,
etc.,) would not have entered into their experiments.

The circuit external to the seat of emf is irrelevant. What is an
"ordinary emf?" Maybe some of the physics people on the list
will discuss emf in quantum mechanical terms before our moderator
pulls the plug on this very OT subject. One thing for certain: emf is
an abbreviation, it is not an acronym.  :-))
