Answer:
Begin by trying to get the paperclips to stick together to form a chain. Do this put holding one paperclip and then putting another next to it. You’ll notice that when you let go the paperclip falls to the table. There is no way to get the paperclips to stick together…unless we add another item.

The materials which get attracted towards a magnet are magnetic – for example, iron, nickel or cobalt. The materials which are not attracted towards a magnet are non-magnetic materials. Examples of non-magnetic materials include rubber, coins, feather and leather.
