How to make a compass.

First we have to figure out the polarity of the magnets

Every magnet has both a north and a south pole.  There are no magnets with only one pole. 
The simplest to use is the Electronic Pole Finder.

If you don't have a pole identifier readily available, 

You can use a little science to find the north pole of your magnets.  Your magnet's north pole is attracted to the Earth's north pole.  Technically, the Earth is labeled backwards -- the magnetic pole near the geographic north pole is actually like the magnetic south pole of a magnet.

If you hang your magnets on a long thread, the magnets will freely rotate.  Once it stops wobbling, the north end should be pointing north.  If you know roughly which direction is north (the sun rises in the East and sets in the West), you'll find your magnet's north pole in between.

A compass needle can be made from any piece of metal that can be magnetized.  You could also try these other "needles":
• A paperclip
• A razor blade
• A safety pin
• A hairpin

Then you need to magnetize your needle (piece of metal) with the magnet.


Then float it on leaf, cork or plastic. 

You just made a compass.
