How do you make a compass with a water and needle?
Have a go
- WHAT YOU NEED: A bowl of water, cork, sewing needle and a compass. 1 of 5.
- Rub the needle 50 times along the magnetic strip on a fridge door.
- Place the magnetised needle onto the piece of cork.
- Gently place the needle and cork into the bowl of water.
- The needle will turn and then come to a complete stop.
How do you make a magnetic compass with water?
Let’s Make a Compass
- Fill the bowl half-way with water and float the “compass” on the surface of the water.
- Place the whole “compass” on a flat surface and watch the needle as it tries to align itself with the magnetic fields.
- Now go test out your new compass and see if you can orient yourself on a map!
How do you make a compass with a needle and a magnet?
DIY COMPASS DIRECTIONS
- Magnetize the needle. Hold the needle, and take your magnet and stroke it down the length of your needle 50 times.
- Magnetize the other end with the reverse.
- Prepare the cork.
- Insert the needle.
- Fill a bowl with water.
- Test the compass!
- Extra fun!
How does a compass needle work?
A compass works by detecting the Earth’s natural magnetic fields. This allows the needle to better react to nearby magnetic fields. Since opposites attract the southern pole of the needle is attracted to the Earth’s natural magnetic north pole. This is how navigators are able to discern north.
How is the compass needle?
A compass needle points north because the north pole of the magnet inside it is attracted to the south pole of Earth’s built-in magnet. Since unlike poles attract, the thing your compass is being attracted to must be a magnetic south pole.
What is the needle of a compass?
The compass needle is a little steel magnet balanced upon a pivot; one end of the needle, which always bears a distinguishing mark, points approximately, but not in general exactly, to the north,’ the vertical plane through the direction of the needle being termed the magnetic meridian.
Can you magnetize a needle without a magnet?
Alternatively, you can magnetize a needle by rubbing it against your hair, some animal fur, or silk. Carefully hold the sharp point of the needle and rub just the eye of the needle 50 to 100 times against the hair, fur, or silk.

How do you make your own magnetic compass?
Fill the bowl half-way with water and float the “compass” on the surface of the water Place the whole “compass” on a flat surface and watch the needle as it tries to align itself with the magnetic fields. The needle should point towards the nearest magnetic pole (north or south) depending on where you live.
How to make a compass out of water?

What’s the best way to float a compass?
Float the compass. Fill a bowl or jar with a few inches of water and place the compass on the water. The magnetized needle will align itself with the earth’s magnetic field to point north to south.
What’s the best way to suspend a compass?
There are two ways to suspend the improvised compass needle. Fill the non-metallic container with a few inches of water. Gently put the magnetized metal on the small piece of cork, wood, or leaf and set them to float. In some situations you can use a small puddle of standing water to float your compass needle.
