I was merely asserting a matter of personal taste here. I hold
that the term "potential" (or "potential difference") pertains
implicitly to a quantity in a conservative field, most commonly
electrical or gravitational. I only use it in an appropriate
context. "Voltage" would be quite satisfactory, but in the case
of an inductor I prefer "emf" or even "back emf". It is hard to
understate the difficulty encountered by the average student
when he first encounters this concept. I like to make it as
easy as I can for him to recognize that this is different from
the electrostatic potential case.
