Question

By which of the following activity, a magnet can loose its property?

• A. Excess of heating
• B. Demagnetizing magnetic field
• C. Sudden shock
• D. All of the above

Answer 1

The correct option is D All of the above

A magnet shows magnetic behaviour because of the presence of domains which are like tiny magnets with a particular orientation.

By all these actions, all the arranged magnetic domains which exhibit magnetic property due to their specific arrangement get rearranged and that specific formation of magnetic domain which is responsible for its magnetic behaviour is destroyed. And hence the magnet will loose its magnetic behaviour.
