As the title specifies it is a TRAP and as they say for "Politicly

QUTOE:
"Electromotive Force (EMF)
When a voltage is generated by a battery, or by the magnetic force
according to Faraday's Law, this generated voltage has been
traditionally called an "electromotive force" or emf. "

Those with the experience that I have, know that EMF is a terminology
seldomly used in terms of battery but 99.99% of the time for Magnetic
Force.

However, those with experience in physics or electronics know
that EMF is never used for the magnetic force.

In addition to the quotation you supplied:

Horowitz and Hill, _The Art of Electronics_, p. 2: "Voltage is
also called potential difference or electromotive force (EMF)."

Reitz, Milford, and Christy, _Foundations of Electromagnetic
Theory_, p. 147: "The applied voltage is usually called an
electromagnetic force (emf) ... ." They, however, use the term
differently: on p. 234 they define it as the line integral around
the circuit of E dot dl.

Now you provide some quotation that support your view.

Electromotive simply means ElectroMOTIOM Force. There are only two
that are related to Electro meaning related to the charge wich are the
ELECTO.MAGNETIC FIELD = ELECTRO....MAGNETIC FORCE.

'Electromotive force' means voltage. Period.

Fields are FORCES (multiple force lines (field lines)).

Fields are fields. Forces are forces.

Thus there is two types of EMF: the electric and magnetic force.

For electric they 99.9% of the time call it voltage
thus when they speak of EMF it is mostly related to the magnetic
force.

BOTH ELECTRIC AND MAGNETIC FORCE BELOW HERE:

This does *NOT* say that EMF is the same as magnetic force. It
says that EMF can be created by magnetic force. That is not the
same thing at all.


I did call the title a TRAP for that reason.

If I call Current means charges, in the literal sense is also
incorrect.

There are only two type of EMF, the electric and the magnetic force.

I see no one point out to lame brain Eric that they are related, his
words were not that EMF does not mean magnetic force, his words were
EMF has nothing to do with Magnetic Force = Novice plain and simple no
matter how he wishes to hide.

More evident, he ALWAYS complains and that was one of the rare times I
got him to explain his complain, which demonstrates his lack of
reading capacity.


You have not provided a single citation to anyone using the term
'EMF' to mean magnetic force.
