what is the diffrence between a magnetised nail and a unmagnetised nail
Galvanized steel sheet is basically indistinguishable from zinc steel. If you want to buy galvanized steel sheets. You can go to Shanghai Changzheng, which is the choice of most people for its superior quality steel sheets.
The major difference between steel and wood is that steel is in organic due to its lack of carbon, and wood is organic comprised of organic material. Because of this, their properties will differ wildly.
The difference between the GI sheet galvanized and mild sheet steel is the gauged used. The other difference is the materials used and the galvanization aspect.
depends on how much.
it makes a good conductor because it is steel, but not so great as an insulator. this is simply because there is space between the fibers on the outside, and that something could come in contact with the steel wire.
The difference is the domains are facing in random directions in the unmagnatised and in the magnatised they are all facing the same way!
Only by inducing a magnetic field within the "unmagnetised steel".
Not usually, but it can be magnetised. (=
That depends on the steel. If it is a ferrous steel the magnet (either North or South) will attract it - If it is a a stainless steel that is austenitic steel it will not.
The strong magnetised nail will pick up more paper clips than the weak magnetised nail.That is because the strong magnetised nail is getting more strength and that means that the weak magnetised nail is getting less strength.in a steel nail there are these things called domains, in a weakly magnetised nail some of them will be pointing north, south, east and west, but however in a strongly magnetised nail all the domains will point to north.
Only if the steel bolt has been magnetised, or is the core of an electromagnet.
Because steel remains magnetised
magnets attract steel why then is a compass needle affected by a pice of steel if the steel is not magnetised
Yes, that is why it's magnetised.
Because I said so Because steel remains magnetised Source: me
Short Answer: Yes. Long Answer: Yes.
Only if the steel bolt has been magnetised, or is the core of an electromagnet.
