Answer 2

Answer:

Magnetize the needle

Hold the needle, and take your magnet and stroke it down the length of your needle 50 times. If you are using a weaker magnet you may need to do this more than 50 times. But for most good quality magnets 50 should be about right.

Magnetize the other end with the reverse

Now this is very important, take note of which side of the magnet you were using. Flip the needle around so you are holding the other end, and flip over the magnet so you are using the other side of the magnet. Now repeat on the non-magnetized end of of the needle.

Prepare the cork

Cut a cork so it is about 1 to 2 cm thick.

Insert the needle

Carefully push the needle through the cork. This is best done by an adult with a pair of pliers. I found it easiest if I used a thumb tack to start the hole, then pushed the needle through. You want the cork to be centered on the needle.

Fill a bowl with water

Set out your bowl and fill it with a few inches of water.

Test the compass!

Place your cork and needle in the water and see how it moves. It should align itself so it points North.

Extra fun!

Create a second compass and add it to the same bowl of water. What happens? What happens if you bring your magnet near the water? What happens if you spin the compass?
