Magnetic E&W poles

Someone told me once that permanent ring magnets have an East and West
pole as well as North and South. Presumably this has something to do
with the orientation of the steel when magnetized. Does this make
sense to anyone? If so, how could the E and W poles of a magnet be
determined?

It sounds to me like someone is pulling your leg.

Just like the Earth, while looking at the North pole the West pole is
on your left. ;-)

I thought the geographic north pole was actually the Earth's magnetic
south pole.
But if you were actually at the "north"pole, you'd have to look down
at your feet in any event to see any other pole.

Not yet.

No one said anything about being at the North pole.

This only works because it is always midnight at the North pole, and
time varies on the EW poles

I know, I was just being a smarty-pants.
Like asking which way is east when you're plopped directly on the pole.

Electric fields result from assorted charges (which are the 'poles')
and there's only two types of such charge. Magnetic fields result
from
circulation (curl, actually) and have poles just like our planet does,
as
the pivot points, or centers of circulation.

Look at the S and you see circulation CW (clockwise), and
look at the N and you see circulation CCW around the center. So
technically
there aren't any E or W poles. Unless you're in an Oz book...

The ring magnets made for motors, however, have usually got multiple
poles printed around the ring. I suppose you could name them anything
you want.

A coil shaped like stitches-on-a-baseball makes four poles,
and the resulting field is actually useful for something (a kind of
magnetic bottle). It seems like you SHOULD be able to give
all four poles their own names.

"Someone" is blowing smoke up your ass.

Technically, there isn't even a "north" or "south" pole - magnetic lines
of force are circles; it's only when there's an intervening permeability
mismatch that the "poles" appear.

Cheers!
