Because the iron used in the needle (A lodestone I think it is sometimes called) is naturally attracted to the magnetic north of the planet, so in theory the compass will always tell you which direction north is.
They use needles and thread to make the clothes.
yes
You can if you seam up the side and it it is a great thing to do for beginners when you have the right pattern, which is the difficult part. Alternatively, if you do not wish to use circular needles you can use DPNs (double pointed needles) to knit in the round. Often in hat patterns which use circular needles you will need DPNs anyway, so it is good to have some of these when you knit in the round.
There is no exactly mentioned reord of when was the first compass ever used. According to historical records, compass is believed to be used at the time of Qin Dynasty(221-206 B.C). The earliest compasses were made of lodestones. This mineral is made of iron oxide which orients itself to a north and south axis.In 1117 Zhu Yu's book Pingzhou Table Talks came out. It was the first time in the history of the compass that the device was mentioned as a tool for navigation. Later in the 8th Century A.D, magnetic needles replaced the loadstones. From the 8th century to 1050's, compass were actively used in ships. Records also prove that Zheng He of Yunnan (1371-1435) used the device during his voyages. Based on the history of the compass, these voyages took place between 1405 to 1433.
A compass.
Steel contains a large proportion of iron which affects compass needles.
Iron needles are good in compasses because they are easily magnetized, allowing them to align with the Earth's magnetic field. This alignment helps to indicate the cardinal directions (north, south, east, west) accurately. Additionally, iron needles are lightweight and durable, making them practical for compass use.
Compass needles are typically made from magnetized materials such as iron or steel. These materials are able to become magnetized and align with the Earth's magnetic field, allowing the compass needle to point north.
Compass needles are typically made from a ferromagnetic material such as steel. Some compass needles may also contain a small amount of cobalt or nickel to enhance their magnetic properties.
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.
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.
Steel is a good material for compass needles because it is magnetized easily and retains its magnetism well. This allows the needle to align with the Earth's magnetic field, which is essential for accurate navigation. Steel also has good mechanical properties, making it strong and durable for repeated use in a compass.

It depends how strong Earth's magnetic force is.
Compass needles are permanent magnets. in response to the Earth's magnetic field, the compass needle will point toward the geographic North Pole.
