In the US a thin wire nail, with almost no head and 3/4" to 2"long is a finish nail. 1/2" long are called brads. note. the UK may have different names for these.
The material will yield when stress reaches a critical value. Stress = Load / Area Thick steel wire is stronger than thin steel wire because there is more cross sectional area in the thick wire. Although the material's strength in load per unit area would be the same, the ultimate load that the wire can sustain would be more in the thick wire. A simple way of looking at it is to imagine a thick wire as a number of thin wires stuck together. If a thin wire can support a mass of 1kg then 2 thin wires can support 2kg. A wire which is twice as thick (twice the cross sectional area) can also support 2kg.
It called cord
shunt field winding are made with many turn of small wire.
Could be a Cap coat or a thin coat is sometimes called a skim coat or feather coat
A thin (smaller diameter) wire resist more electricity than a thick (larger diameter) wire. Just like a larger pipe will allow more water to flow than a smaller pipe, a larger wire has more cross-sectional area to allow more current to flow.

A headless nail can be a derogatory term for someone who takes on a task, but won't accept responsibility. Or it could be a brad nail, which is a thin nail made from wire, that may have a slight head, a spur to one side, or no head at all.
a thin pointed piece of metal is called a spike

it is called an electromagnet
To measure the thickness of a thin piece of wire we have got the instrument called the wire gauge. The thickness of a thin piece of wire is measured in mm.
If the bent nail is used to fix a plain wire or strand of barbed wire to a fence post, and the bent nail is pointed on both ends, then it is a staple.
This area of skin is called the cuticle

Copper Wire
Connect a long, thin piece of copper wire to the ends of your battery. (Long and thin so it won't burn up before you use it.) Then wave the nail back and forth fast many time very very near the wire. Two things happen. 1. Electricity is generated in the nail 2. The iron in the nail slowly takes on magnetism You get better result if your wind many many turns of copper wire around, say, a pencil, so you have a coil, and wave the nail back forth near the coil. Also, you can point a nail north, and tap on it with a hammer, or something, and the iron in the nail eventually will become magnetized. This happens to ships at sea, and they sometimes have to be deGuassed in a huge drydock. DeGuassing is a method to remove magetism.
