Why do magnetic materials exhibit magnetic properety?

Question

Only some metals are magnetic. What is the reason for metals like iron to show property of magnetism?

Answer 1

In addition to alignment the magnetic materials don't "hold on" to their electrons as much as non-magnetic materials. It is this freedom of the electrons to move that allows for the magnetism because magnetism arises from the movement of electrically charged particles (such as electrons).

Answer 2

bcoz the atoms in metals align themselves
where as in other materials atoms r so hither tither that they cant align themselves
