Cobalt, Nickel, Iron and alloys including any of those metals
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.
Magnetic materials are magnetized by exposing them to a magnetic field, such as from a magnet or an electromagnet. This causes the magnetic domains within the material to align, creating a net magnetic field. The material retains this magnetic field even after the external field is removed.
Only by inducing a magnetic field within the "unmagnetised steel".
When a magnetic material is magnetized, its magnetic domains align in a specific direction, creating a net magnetic field within the material. This alignment results in the material becoming capable of attracting or repelling other magnetic materials.
Temporary magnets are typically made from materials like soft iron or steel, which can be easily magnetized and demagnetized. These materials have high magnetic permeability, allowing them to quickly align their magnetic domains in the presence of an external magnetic field.
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).

Diamagnetic substances are not magnetised. Example: water is a diamagnetic substance, so it cannot be magnetised by any means.
rub a magnet on it in the same way but the material has to be magnetised :)
Only if the steel bolt has been magnetised, or is the core of an electromagnet.
A Weakly magnetised nail will pick up less paper clips then a highly magnetised nail, Hope That Helps:)
Only if the steel bolt has been magnetised, or is the core of an electromagnet.
You can put a magnet near the metal. If it gets attracted or repelled, then it is magnetised
No. Mercury is not a magnetic substance nor can it be magnetised. Iron, Cobalt and Nickel are the only ones.
An electromagnet is only live (magnetised) when a current is flowing through the coil.
No.
what is the diffrence between a magnetised nail and a unmagnetised nail
