Answer:
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:
Rusting of iron is chemical change as there is oxidation of iron from Fe to Fe2O3 and is irreversible where as magnetization is physical change as no chemical process involved,there is no change of state,temperature,smell or evolution of gas and it is reversible.
