Making Magnets

On Friday before Spring Break, after looking at magnets several times over the term, we decided it was time for us to make our own magnets.  To do this we put a nail on a strong magnet and kept it there for over 100 seconds. We counted by ones to get there. Then we removed the nail from the magnet and tried to see if it could work. Check the photos below to see how it turned out.

The question is... do you know why it worked? We do!
