Yes, a steel nail can become demagnetized. This can occur through several methods, such as exposing the nail to high temperatures, which disrupts the alignment of its magnetic domains, or by subjecting it to a strong opposing magnetic field that can realign the domains in a way that cancels out its magnetization. Additionally, physical impact or vibration can also cause the magnetic properties of the nail to diminish.
If we take a steel nail and tap it with a magnet in the same way a bunch of times, the magnet will align some of the magnetic domains in the nail. The nail will then have become a permanent magnet. The magnetic strength of the nail will not be great like the magnet that created it, but it will be present and will be permanent. The nail could then be used to pick up iron filings just as the magnet could be used to do that.
The hardness of a steel nail is about 4.5 (About the same hardness of the mineral Fluorite.)
In an un-magnetised nail there are tiny domains, each in themselves would be a little magnet, however, in a magnetized steel nail the magnetic "domains" tend to be lined up in the same direction. A domain is a tiny magnet because electrons are spinning with the same orientation. Refer to the related link in the Related Links section below for more details.
Typically you can magnetize iron or steel by exposing it to a strong magnetic field. Common "ceramic" magnets may not be strong enough, but you may need a strong rare earth magnet or a strong electro magnet.
Iron has a density of approximately 7.86g/cm3. Nails are not usually made from pure iron, but from soft steel, a mixture of iron and carbon. The density, however, is pretty much the same depending on the grade of steel used.
No it isn't!!
The homograph of "nail" is "nail." In this case, the same spelling is used for both meanings of the word.
A piece of metal can be magnetized if the atoms of which it is composed are magnetic, and they have aligned their north-south poles to point in the same direction. Heat increases atomic vibration and will cause these atoms to lose their alignment and point in all different directions, so that their atomic magnetic fields will not combine to form one large magnetic field.
The difference is nail polish, is basicly nail paint....But nail varnish is like the special nail paint they use to make designs on your nails. - - - - - Nail polish, nail varnish, nail paint and nail lacquer are four names for the same stuff. It just comes down to what the manufacturer wants to call it.
They are basicaly the same. I believe nail lacquer is just thicker.
The ingreadiants in Nail polish is almost the same as in a noqualer bomb
Nail gun.
