Magnetization of iron is a physical change and not a chemical change as there is no change of state, no change of temperature, no smell and no evolution of gas. It is because: - No Chemical process is involved. - After demagnetizing the iron it will lose its magnetic power.

Answer:
Magnets are well - know from the physics lessons at school , but they are Hardly covered in chemistry lectures ; and it is still a chemical process by means of which researchers have succeeded in controlling magnetic properties in bulk ferromagnets
