Iron is magnetic
A compass saw is used to make curved cuts

A compass is used to make a perfect circle.
Some are possible, others are not.
you first measure it on your protractor correctly then you use it:)
Iron reacts with oxygen and water to form rust. Not a good thing for a compass.
It is magnetic and would throw off your little dial
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.
It could not be used because it attracts magnets and a compass is a specialist form of magnet, utilising the magnetic properties of the earth to give a reading. Compass housings are invariably made of brass, aluminium or plastic.

A small iron nail
what the quartz means is the quartz nail. No, a quartz nail is not the most useful to make a compass. A small iron nail is useful to help make a simple compass
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.
Weapons (arrow heads, blades), navigation (compass), construction (nails)...
well the first person to make the compass was the chinese.
sun dial + glass = compass
Get a decent size magnet. Get some iron filaments and sprinkle the iron filaments around the magnet. You will see the magnetic field of the magnet from the iron filaments lining up from each pole and curving outwards.
