Rubbing only about ½” on the end of the paperclip should do just fine. In order to tell ad disc magnet’s polarity using a compass, you will need to gather a regular compass and the disc magnet that is in question. Traditional compass needles are raised above the surface as well, eliminating any friction for the most accurate reading. The key to making your compass work is rubbing the magnetic poles of your magnet on opposite ends of the needle. A Compass: The earth can be pictured as a gigantic magnet, but the geographic North Pole actually is the South Pole of a neodymium magnet. 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. To make a floating magnet we’ll need some other things: A tub of water, a foam tray, a knife, and a permanent marker. Now that’s cool. Both ends of the needle should be above the floating paper circle. However, the compass seems to work according to this video.

Now, fill it about halfway with water and float the cap in the center so that the smooth, flat side is facing up. 4. Note that hard drive magnets are usually not useful for making a compass because they will have both poles on the same face of the magnet. 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. Jacob N. Bailey courtesy of US Air Force. Having the wax paper float on water allows the needle to move without friction. Hang the bar vertically and hit it repeatedly with a hammer. The magnetizing effect is stronger if you heat the rod. ** ** Your device must have MAGNETIC SENSOR inside to read earth magnetic field. Wait a minute, and you will find the magnet’s North Pole is pointing north! After the knot is completed cut off any remaining string left in the knot. If a magnetometer is not necessary for the compass to work, then why do all the other phones have one? Keep the magnet separated from the knife. In order to ensure the maintenance of a magnetic compass in good working condition, it is recommended that repairs to a compass be made by the compass manufacturer or other competent person using proper test facilities in accordance with the rules for testing and certification of magnetic compasses contained in ISO 25862:2009. You cannot create compass feature without involving magnetic sensor. The compass automatically aligns itself with these invisible magnetic lines. Photo: A magnetic compass points north because it aligns itself with the magnetic field produced inside Earth. This … 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. The simplest compass is a magnetized metal needle mounted in such a way that it can spin freely. I will put the magnet on top of sterofoam, then put it on calm water. Print out detailed instructions and a supplies list below and preview the experiment with our demonstration video. Induce a magnetic field with an electric current. Magnetic compass has compass rose or a windrose, which is used to display the orientation of the cardinal directions: North, East, South and West and their intermediate points. Attach the string to the O-ring by tying a knot. You’ve made a simple compass! 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). Fill a wide cup, drinking glass or bowl with at least one inch of water. Now just sit it inside the bowl of water and watch it... is it north or is it south? You use this form to shield your compass from the other two by inducing "magnetic variation" with magnets and iron bars. 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 If two magnets are brought together, the north pole of one will attract the south pole of the other. Step 1: Get the compass case ready. Photo by Staff Sgt. Place the needle on a small leaf (Or piece of tissue paper) and gently put on the surface of the water. This creates a magnet! 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. Place thermocol on the water and a bar magnet. ** Use just like a real 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. a sewing needle; a magnet (preferably a 'bar' magnet, though a refrigerator magnet will do) Step 1: Rub one end of the needle on the positive side of the magnet and the other end on the negative side. The compass reacts with the earth’s poles to point in the direction of the earth’s North Pole. Step 2: Magnetize the Needle. It can't be the gyroscope as the compass responds to the magnet. Making a compass in the wild can be done using a sewing needle, a magnet and some stagnant water, or it can be done using the shadows of the sun to find east and west. Experimenting to gain a understanding of magnetic forces, we came across this very simple way to make a hanging magnetic compass needle out of only 5 pieces w… When the compass is used with a map, compass is leveled horizontally and left for a magnetic needle to find the North. Place the paper and needle on the surface of the water. But you need to be aware of one secret rule that can cause any compass to go haywire!
