Screwdrivers are sometimes magnetized to help hold screws in place, making it easier to start and drive them into surfaces. The magnetic tip can also assist in retrieving dropped screws or small metal objects in hard-to-reach places.
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).

Metals can be magnetised which can produce an attractive force.
A simple block of magnetized iron is called a magnet.
magnets attract steel why then is a compass needle affected by a pice of steel if the steel is not magnetised
A Weakly magnetised nail will pick up less paper clips then a highly magnetised nail, Hope That Helps:)
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.
You can put a magnet near the metal. If it gets attracted or repelled, then it is magnetised
No.
Diamagnetic substances are not magnetised. Example: water is a diamagnetic substance, so it cannot be magnetised by any means.
what is the diffrence between a magnetised nail and a unmagnetised nail
I couldn't exist without a good set of screwdrivers.
Hex, or Allen screwdrivers are for screwing and unscrewing Allen head screws.
Jewelers screwdrivers are very small examples of normal screwdrivers, watchmakers use them too.
lead is an inert metal and can not be magnetised

Screwdrivers can cost as little as a dollar. In all tools you get what you pay for. I have $15 dollar screwdrivers that have lasted over 20 years and I've broken many 1 dollar screwdrivers.
