Re: [femm] Re: FEMM simulations errors ??



The North pole of the earth is the north magnetic pole.
The pole of a compass pointing north is a south pole because
the compass magnet is aligned to the EXTERNAL field of the
"earth magnet".  The north of the compass is pointing in the flow
direction of the field of the earth flowing from north to south.
You have to remember that the field you are embedded in
is a field flowing out of the north pole down TO the south
pole.  The compass aligns to the flow DIRECTION meaning
the north of the compass points south.  The north of the compass
would only point north if you could stand in the center of the
earth.  Then the flow direction would be toward the north pole.

Hope this helps,
Dave Squires

[Moderator Note: Actually, this is the other way around--the geographic north pole is actually a magnetic south pole. A nice page with respect to this is: http://www.execpc.com/~rhoadley/magpole.htm ]

Just curious, but is a North pole the same field as emanates from the Earth?s North pole, or the field that comes from a compass? North pointing end?

Thanks
