Rub the needle across a magnetic surface...always in the same direction, don't go back and forth. This will magnetise the needle. Then float the needle in a dish of water. And presto you have your own compass

How do you magnetise a needle?
You need to rub the needle with a magnet or you can use coil around the needle and pass current to make it a electro magnet.
What must be done first to an ordinary sewing needle to make it a compass needle?
Magnetize it. Rubbing it in one direction against a magnet will do that.
What is the material to make a compass needle gold silver iron or copper?
Are you asking what material is a compass needle made from? It that is your question, you need to keep in mind that the material used must have magnetic properties. Research the Iron Triad from the Periodic Table.
Is it possible to magnetise an object permanently?
Yes, however the object must be a magnetiseable metal such as iron. To magnetise it you could use a permanent magnet and slide it along the metal pice in one direction several times. Than you pice of iron for example would be a permanent magnet. Another way of doing this is, if there is no permanent magnet available, is to use a SOLENOID. You could build yourself one: Check it out on the internet. This solenoid would make your pice of iron permanently magnetic with the use of ELECTRICITY. This shows that magnetism and electricity are closely related. GUD LUCK and I hope my answer helped you.
Why won't my compass work?
First make sure that your compass is flat on your hane/arm/ground also please go to my website- www.toppicks.webs.com

How do you make a compass from scratch?
magnetize a needle by rubbing it on a magnet. Lie the needle in a shallow container of water, allowing the surface tension to keep the needle afloat. The needle will orient to north and south
How can you make a compass needle face the wrong way?
you cant really because the magnet in the compass controls and direct it the way it needs to go

How much does a compass cost to make?
cheap compasses can be around 3$, but more high-tech traveling compasses are usually around 30-60$
Hot can you make a compass?
There are a few different kinds of compass. To make a compass that makes circles you could use a pencil and tie it to another pencil and trace circles.
Could you make needle felt at home or in school?
depends who you are
How do sailors navigate the ocean without a compass?
Since the needle on the compass is orient to due north the compass was used in concert with a sextant to prepare route maps. The compasses were used to make sure that north on the map was properly oriented.
A compass needle changes direction if the flow of electricity in the wire near it is reversed.?
The only way to make current flow through a compass needle is to connect a wire to each end of the needle. When you do that, the direction the needle points is completely determined by the wires, and it's no longer free to rotate. So I'd say that nothing at all interesting happens.
Does the red arrow on a compass point to were i am?
Half of the needle is painted red to indicate the direction of North. The red orienting arrow is marked on the floor of the housing. It rotates with the housing when the dial is turned. You use it to orient a compass to a map.
What does a opposite rays look like?
like a compass needle, north and south are opposite rays on the needle. same for west and east. 2 opposite rays always make a line, and they share the same endpoint <-----------@--------------@------------> (the @ sign is the endpoint of one of the rays)
