Here's a reference from a company that produces permanent magnets. They
explain the cause of magnetism in the permanent magnet:

http://www.arnoldmagnetics.com/mtc/pm_manual_chap_1.htm

"Magnetic fields from permanent magnets arise from two atomic sources: the
spin and orbital motions of electrons. Therefore, the magnetic
characteristics of a material may change as a function of alloying with
other elements. For example, a non-magnetic material such as aluminum can
become magnetic in materials such as alnico or manganese-aluminum-carbon. It
may also change from mechanical working or any other stress to the crystal
lattice."

The orbital motion as well as the spin are regarded as electrical currents.
By definition I= dQ/dt (the current is equal to the change in charge with
regard to time at a specific location). If a charge moves, it is current, it
is electricity. For example, solar flares are huge charge ejections that
create magnetic fields with no conductor involved.

Remember the electric and magnetic field of the sun is so small it can't
possibly knock out satellites, let alone affect power grids here on earth!

The gravitational field follows the same decay rate as the electric field
from a charged sphere. Hence, the gravitational field of the sun or moon is
so weak it can't affect us here on earth!

Sunlight is so weak in field strength (it's an electromagnetic wave too) it
can't possible cause cancer!

Amen!

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
effects
on
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?
