Yes, it is possible.
Steel Wire in most cases but they can be made of plastic, or aluminum.
Copper isn't magnetic.
No. Copper wire is made of the element copper. Tungsten wire is made of the element tungsten. Copper wire is made to conduct electricity. Tungsten wire is made for the filament in light bulbs as tungsten does not melt under even very high temperatures.
No, most paper clips are made from steel wire or plastic.
Copper wire is made of the element copper. Copper is a pure substance, not a compound, because it is made up of only one type of atom.
Copper
The copper wire has to be wound around a iron core to get the full effect of electromagnetism.
copper wire
copper and tin
castings made from copper alloy are a higher grade of copper than the copper in wire. Also, the insulation on the copper wire needs to be removed,
Copper. The wire is made of elemntal copper not a chemical compound. (Note the copper used may sometimes be alloyed with another metal or occasionally be a solid solution of small amounts of oxide in the pure metal. This improves the durability and handling characteristics of the wire.)
Copper wire is a substance because it is made up of a single type of material, which is copper. It is not a mixture of different substances.
