Answer 1

Magnets are materials that produce magnetic field and attract other materials, that can be magnetised – called ferromagnetic materials, to them. Iron, nickel, cobalt etc. are some examples of ferromagnetic materials. Magnets have the property of repelling other magnets, when their similar poles are brought close to each other.  

Ancient people found naturally occurring pieces of magnets on earth, which attracted pieces of iron. These naturally-magnetised minerals are known as magnetite or lode stone.
