magnetic

How do magnets work? How are they related to the earth? Do they behave differently on the moon? Why can a person with a magnet and a piece of metal turn the metal into a magnet using friction, by rubbing the two objects together? How does that happen? How do the magnet's poles, positive (+) and negative (-), get affixed to the pieces of metal? Do magnets and gravity have anything in common? Do magnets have other uses besides attaching pictures, comics, and reminders to the refrigerator?

How does magnetism work between living creatures? Is it the same thing, or the application of the same term ('magnetic') to a different, more biophysical phenomenon?
