Iron needles are good for compasses because it is thin, and light
When you put three compasses together, they will each align themselves with Earth's magnetic field, pointing in the same direction. This is because the compass needles are magnetized and respond to the Earth's magnetic poles. You'll see all three compasses pointing in the same direction, indicating north.
In the past, magnets were used for compasses for navigation, including in exploration and sailing expeditions. They were also used in tools such as magnetic needles and magnetized chisels for various purposes.
Without the specific figure to refer to, I can provide a general answer. Compass needles will align themselves along the magnetic field lines of a magnet. If the iron nail is magnetized, the compass needles will point towards the ends of the nail, indicating the presence of a magnetic field. If the nail is not magnetized, the compass needles will show no significant movement around it.
Compasses do not detect fluctuations in convection in the mantle. Compasses align with Earth's magnetic field, which is generated by the movement of molten iron in the outer core. Convection in the mantle occurs in the solid rock layer above the outer core, and does not directly influence the magnetic field detected by a compass.
Pyrrhotite is a magnetic mineral that naturally attracts iron due to its magnetic properties. This makes it useful in applications where magnetic properties are desirable, such as in compasses or magnetic storage devices.
Lodestone
If you bring two compasses next to each other, the magnetic fields of the compass needles will interact. The magnetic needles will align themselves in opposite directions, causing the compass needles to repel each other.
The needles of compasses are typically made from magnetic materials such as steel or iron. These materials can be magnetized and align with the Earth's magnetic field, allowing the compass to point in the direction of magnetic north.

people uses compasses because it is a very good use of tool that tells you where to go when you are lost.
The plural possessive for compasses is compasses'.
compasses have Mineral Oil filled Needle Housings, with steel needles that pivot on a sapphire bearing The light mineral oil is there to damp the needle (stop the needle swinging too loosely) and it has to withstand freezing (because compasses are used in cold places).
Yes, a coin is a conductor because it is made out of metal, as well as keys, sewing needles, and iron nails are all conductors.

There are two main types: Magnetic compasses and gyro compasses.
