No.
yes
an iron nail
An iron nail will be attracted to magnets. But it itself will not attract other metals unless it has been magnetized through a certain procedure.
if a nail has any iron in it, it will be attacted to a magnet. Most nails are made of steel, a substance created from iron.
An iron nail is more strongly attracted to the magnet than to the wooden box the magnet is stored in.
They are of the same hardness, so I believe not. that depends how wet and thin the iron is. the nail's usually thin, unless it is a hardware nail. the best thing to cut a nail with is a diamond's (the hardest material) sharp edge.
No. Only another diamond can scratch a diamond.
