Question

megnetize a piece of iron is physical change or chemical change ​

Answer 1

Answer:

Physical Change

Explanation:

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. Attracting iron towards a magnet does not change the substance (change of the composition) itself and doesn't involve chemical reactions.
