Could you apply this same kind of wonderfully clear exegesis to
the term "magnetic lines of force"? I keep seeing intimations
that they have some kind of reality. Thank you!

There are no lines of force that manifest themselves physically in time
and space. It is just a dumb term for magnetic field that someone
invented when watching the lines of clumped iron filings. This has
confused many people. Just ask yourself what is between two lines of
force or can you have a one half line of force.
