Copper
Every thing except a conducting wire, battery and a soft iron core is not needed for making an electromagnet
Copper is used because it is a good conductor of heat and thus more energy efficient. The solder melts at a temperature lower than copper and the soldering iron is controlled to only reach a high enough temperature to melt the solder. There are metals that are more efficient at conducting heat, But considering the melting point of copper, it high availability and relative cost. Copper is by far the obvious choice to use in a soldering iron.
Iron ore is used to make steel
Iron is an element. Nothing is used in it.
There are many objects that can be used for conducting heat, one of the main ones is, metals such as iron. gold, etc. There are also few plastics that conduct heat as well.
copper aluminium iron and steel is an excellent conductor of electricity and heat is one of the properties of copper aluminium iron and steel and it is used in conducting electricity.
Yes, Of course Iron is the one on conducting material. Although other metals like copper are very strong conductors compared to Iron.
non ferrous minerals are those minerals which do not contain an appreciable amount of iron. These generally do not show magnetic or conducting properties .
Copper (Cu)
s strong short lasting magnet that can be made by inserting iron into a wire coil that is conducting an electric current.
aluminium is very good at conducting heat but iron no
Iron 59 is used in medicine as iron suppliments for people with a lack of iron in their blood stream
The iron clamp is an iron ring with a bolt and nut to tighten it. It is used in conjunction with an iron stand and is used to elevate equipment.
