I see what you mean. Each electron orbit is a closed circuit.
Does emf play some role in propelling an electron through its orbit?

The flux must cross a closed conductor (loop) for current to flow. But
that
is pertinent to a permanent magnet.

Atoms have magnetic fields from the electron orbits. The electron is in
motion around the nucleus in a closed path. The electron, through its
motion, is a current and generates a magnetic field. If enough atoms are
in
correct alignemnt you have a net magnetic field.

A permanent magnet does have current flow.

I believe the Swedes did a study that showed there were know ill

people, but I would pass on it if it were overhead. I believe their
study
was directly overhead. 200 feet probably wouldn't be an issue. More
investigation is, of course, warranted.

Makes one wonder about the magic magnetic bracelets and bands people
wear
for pain management. Why would magnetic flux be a miracle cure when
produced
by a permanent magnet but not when produced by current flow?
