What type of change occurs when an iron piece is magnetized? Give reasons.
Answers
Answer:
Explanation:
Electromagnetic change
The electrons are diverted from alignment when an iron piece is magnetized.
Explanation:
Magnetization of iron occurs only in one direction due to the temporary alignment of electrons present in it. This is done by rubbing the magnet's north pole towards its end in the middle of the magnet. It's temporary because, after a while, the electrons are diverted from alignment. Iron magnetisation is a physical change and not a chemical change because there is no change in state, no change in temperature, no odor and no evolution in gas. No chemical process is involved. The reason behind is since it is a temporary process and it is reversible and no new material is created when magnetising a steel. After the iron has been demagnetized it will lose its magnetic strength.
