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 wouold a permanently magnetic substance called?
No magnet is permanently magnetised. If it is dropped from a great height enough times or heated, it loses it's magentism.
Is magnesium magnectic?
Magnesium is described as "paramagnetic" meaning it is weakly attracted by a magnet and cannot be permanently magnetised.
What does it mean by steel is magnetically hard?
A magnetically hard substance is one which can be permanently magnetised using a strong magnetic force. Steel is one such substance. (A magnetically soft substance can only be magnetised temporarily.)
What does de-magnetised mean?
lost its magnetic field.
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 'permanently' be a synonym for 'constantly'?
No, because permanently is "always" and constantly is "again and again" but constantly does not mean permanently
Can wood be magnetised partially?
No.
What materials are nonmagnetized?
Diamagnetic substances are not magnetised. Example: water is a diamagnetic substance, so it cannot be magnetised by any means.
What is the diffrent between a magnetised steel nail and an unmagnetised steel nail?
