How do you magnetise a needle?
You need to rub the needle with a magnet or you can use coil around the needle and pass current to make it a electro magnet.
Does coil of wire with current passing through it magnetise a piece of iron?
yes it does the current flows in a wire it creates a magnetic field around the wire.

What are hard and soft materials?
The magnetic materials which can magnetise and de-magnetise easily are called "soft magnetic materials" example:-ferrites,iron-cobalt alloy. The magnetic materials which cannot magnetise and de-magnetise easily are called "hard magnetic materials" example:-aluminium(al),nickel-cobalt alloy.

SeeMagnetic purification apparatusUnited States Patent 6103113As an example of how to purify water from a river by precipitating the impurities with a magnetic particle containing flocculant and then filtering passing the water through a magnetic field
Can you de-magnetise a magnet by putting it in hot water?
Sort of. Magnets become weaker with heat, but boiling water is not enough to completely demagnetize unless it was a very weak magnet to begin with. It will become weaker, but the only fool-proof way is to make it borderline molten, completely randomizing the domains.
