Alan,
Let me say first I like your webpage design, it is colourful and easy to read.
As for the compass information - are you sure you are right? If you use a guass meter on a compass it shows the north pole of the compass to be a north pole. What we call the earth's magnetic north is in fact the south pole of a magnet.
I'd appreciate your comments.
regards Bill Smith.

Dear Bill,
Thank you for the imput. I have to admit, I never did put a meter on a compass needle, but you did, it means of course the northern hemisphere is a south field and the southern hemisphere is a northern field. I added an addendum to the page How a compass really works. Alan...
