Decide what to use for your compass needle. A compass needle can be made form any piece of metal that can be magnetized. A sewing needle is a straightforward, practical choice, especially since it's an item you'd normally find in a first aid or survival kit that you might have on hand on a backpacking trip. You could also try these other "needles":
You will need any kind of metal pin you can find like;
1.) a paper clip
2.) a razor blade
3.) or a safety pin
Choose a needle "magnetize r." You can magnetize your needle using a variety of methods: tapping it with a piece of steel or iron, rubbing it with a magnet, or rubbing it on another item that magnetizes it with static electricity.
You will need any kind of magnet you can find.
Gather additional materials. In addition to a needle and a magnetizer, you'll need a bowl or jar, some water, and a coin-sized cross section of cork.
Magnetize the needle. Whether you're using a sewing needle or another metal item, rub the item with the magnet. Stroke the needle in the same direction, rather than back and forth, using steady, even strokes. After 50 strokes, the needle will be magnetized.
