Cut the end off a cork, about 1/4-inch thick, so that you end up with a disk. In order for the needle to act as a compass, it needs to be placed in an environment with less friction, which in this case is the water. The simplest compass is a magnetized metal needle mounted in such a way that it can spin freely. Now just sit it inside the bowl of water and watch it... is it north or is it south? This is especially important if you are dealing with overcast weather, thick forests, or any other conditions that would eliminate a lot of modern navigational techniques. Place the paper and needle on the surface of the water. Jacob N. Bailey courtesy of US Air Force. I will put the magnet on top of sterofoam, then put it on calm water. Magnetise the needle by stroking it (Say 40 times) in one direction with the same side of a magnet each time. With a compass, you can find out which way a magnetic pole is—and from that, you can approximate other directions such as where south, east and west are as well. Both ends of the needle should be above the floating paper circle. You only need a few materials: a tea light (candle), a magnet, tape and a bowl of water. Rubbing only about ½” on the end of the paperclip should do just fine. How to Make a Compass Step 1: Make a Cork Disk. Materials. A needle ; A cork or small piece of Styrofoam that will float flat (i.e., without bobbling around a lot) A paper cup, empty yogurt container, or pie plate With a compass the game is a hell of a lot easier but remember the map is just a simple 5x5 grid. Having the wax paper float on water allows the needle to move without friction. You’ve made a simple compass! This is why compasses work on the Earth.

Now carefully pick up the bowl of water and try to move around so that the “N” part of the floating magnet points in a different direction. This happens because the earth itself acts as a huge magnet with lines of force running between the North and South Poles. Step 1: Get the compass case ready. Hang the bar vertically and hit it repeatedly with a hammer. The needle points north because of the residual magnetic material left on the needle, which should align with Earth’s magnetic field. If two magnets are brought together, the north pole of one will attract the south pole of the other. To make a floating magnet we’ll need some other things: A tub of water, a foam tray, a knife, and a permanent marker. 4. Did you know you can make a compass out of a needle?

Step 1: Rub one end of the needle on the positive side of the magnet and the other end on the negative side. As we do this this arrangement, Bar magnet starts to rotate and finally it shows north pole and south pole. Fill a wide cup, drinking glass or bowl with at least one inch of water. The key to making your compass work is rubbing the magnetic poles of your magnet on opposite ends of the needle. Instructions. A Compass. Now that’s cool. Items Needed. The paint will help us tell the difference between the poles and while they dry you can move onto the next steps. The sterofoam size should not to big, yet big enough to keep it and the magnet floating. Magnetic Pole Identifier. In this project, students use an heat to make a magnet that will function as a compass more easily that the compass in Make a Compass I because it is lighter. For this reason, the North Pole of the magnet will point to the South Pole of the compass. ** ** Your device must have MAGNETIC SENSOR inside to read earth magnetic field. Make sure you magnetized it by trying to pick up another paperclip. The magnetizing effect is stronger if you heat the rod. Rub the rod with two magnets, drawing the north pole of one magnet from the center of the rod to one end while you draw the south pole of the other magnet in the opposite direction. Just float the bar magnet on a little piece of wood in a bucket of water. ** Use just like a real compass. Rub the end of the paperclip (without the hook) against the magnet back and forth at least 30 times. It can have between 4 and 32 points. Rubbing the magnet against the needle in one direction caused the iron atoms in the object to line up and create a weak magnetic field, which made the needle behave like a magnet. Push the needle all the way through the disk so that about the same amount of needle shows on either side of the disk. When the compass is used with a map, compass is leveled horizontally and left for a magnetic needle to find the North. Wait a minute, and you will find the magnet’s North Pole is pointing north! Photo by Staff Sgt.

The compass reacts with the earth’s poles to point in the direction of the earth’s North Pole. Together, these are called “magnetic variation.” The third form is sub-permanent magnetism, the kind that happens when you carelessly leave a tool by the compass. The Earth’s magnetic field is strong enough to make the north pole of a very light compass needle align with the magnetic south pole of the planet. GPS will not help here either and it would only let you calculate the direction you are moving to (and as you'd need at least two different coords you cannot do that while standing).
