Get a needle and a magnet. Try getting a magnet off the fridge if you cant find one but not a flat sheet type or sticker type of magnet.
Hold the needle and rub the magnet from 1 end to the other. only rub 1 way so dont draw it back down the needle. Dont change the ends of the magnet either.
Do this a number of times and the needle will become magnetized.

I may not have explained this clearly, but I hope you can understand.
