Question

can a magnet be used to magnetize a piece of iron and how

Answer 1

As long as a metal has some iron in it, you can magnetize it using another magnetic metal or an electromagnet. While you need a strong magnet to make another metal magnetic, the magnetism produce will probably not be very strong; it will be sufficient to pick up a paperclip or a screw.
