Question

Which of the following natural phenomenon can cause the formation of a permanent magnet from an iron ore?

• A. Lightning
• B. Thunder
• C. Light
• D. None of the above

Answer 1

The correct option is A

Lightning

Thunder is a big sound due to the sudden expansion of air. Sound does not have any effect on the formation of a permanent magnet. Lightning is a flash of electricity produced in the sky during storms or heavy rain. When lightning strikes at a piece of iron ore, a permanent magnet is formed. During the passage of electricity, particles of iron ore aligns in a particular direction resulting in the formation of permanent magnets.
