Is there a limit to how strongly magnetised an iron nail can get?
Yes, every material has its limit in this respect.
What are the only materials that can be magnetised?
Cobalt, Nickel, Iron and alloys including any of those metals
How is the arrangement of domains different in a magnetised and a non magnetised piece of iorn?
In an unmagnetised piece of iron, these magnetic domains are arranged randomly and point in lots of different directions - they cancel each other out. In a magnetised piece of iron, all these domains point in the same direction. This makes one end of the magnet act as a north pole and the other end act as a south pole. The better the domains are aligned, the stronger the magnet. Bye bye!
What object that attracts iron?
none of them. iron can be magnetised but the material itself is not magnetic
What is the difference between a weakly magnetised nail and a strongly magnetised nail?
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.
What can be magnetised?
ferro magnetic substances can be magnetised. but it is not necessary that all the Ferro magnetic substances can be permanently magnetised. it depends on the alignment of domains in the substance.for example wrought iron can be magnetised permanently but soft iron can only be magnetised temporarily(Electro Magnets).
Can all metals be magnetised?
iron nickel and colbolt
Why do steel and iron attract each other?
Metals can be magnetised which can produce an attractive force.
Why is iron a better core material than steel?
Because steel remains magnetised
Is there a limit to how strongly magnetised an iron nail can get?
Yes, every material has its limit in this respect.
What happens to the domains in a piece of iron when it becomes magnetised?
The iron automatically divides into domains separately. It does not exist in a state when magnetization occurs in the same direction, in the entire material. This is to minimize its internal energy.
What are the only materials that can be magnetised?
Cobalt, Nickel, Iron and alloys including any of those metals
How do you magnetise a iron bar?
If you wrap a length of wire around the iron bar then pass a current through the wire, the bar will become magnetised.
Why is iron better core then steel?
Because I said so Because steel remains magnetised Source: me
Is Mercury has magnetic properties?
No. Mercury is not a magnetic substance nor can it be magnetised. Iron, Cobalt and Nickel are the only ones.
Is steel atracted to a magnet?
Contrary to popular belief, most metals cannot be magnetised. The only common metals that can be magnetised are iron, cobalt and nickel. Mild steel, an alloy that contains over 98% iron, can also be magnetised because of its high iron content. Some steels, such as some stainless steels, have larger percentages of other metals which prevent them from being magnetised the same way.
