It means that a substance has all of its magnetic domains pointing in the same direction. This means that the positive and negative ends of each molecule are aligned in the same orientation. This creates a a unified magnetic field. When the charged ends point in random directions they cancel each other out and it is not magnetic. You can magnetize a metallic substance (usually iron) by putting it in contact with a permanent magnet or running electricity through a wire wrapped around it. This is called a temporary magnet.

What is the difference between a weakly magnetised nail and a strongly magnetised nails?
A Weakly magnetised nail will pick up less paper clips then a highly magnetised nail, Hope That Helps:)
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.
How would you determine if a metal is magnetised?
You can put a magnet near the metal. If it gets attracted or repelled, then it is magnetised
Can wood be magnetised partially?
No.
What is the diffrent between a magnetised steel nail and an unmagnetised steel nail?
what is the diffrence between a magnetised nail and a unmagnetised nail
What materials are nonmagnetized?
Diamagnetic substances are not magnetised. Example: water is a diamagnetic substance, so it cannot be magnetised by any means.
Is lead magnetc?
lead is an inert metal and can not be magnetised
When some thing is magnetised what does it become?
Activety site
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).
What types of magnetize but lose magnerism quikly?
If you mean what metals magnetise and demagnetise quickly, soft iron is a good one. It is a good core for an electromagnet because it demagnetises when switched off. Hard iron, ie steel, will remain magnetised and remain magnetised until something drastic like melting it occurs. Hope this helps.
Do paper clips get magnetised if it comes in to contact with an electromagnet?
Yes they do.
Is there evidance that the rocks of the ocean floor are magnetised by the earth's field?
no
