Question

The magnetism of a magnet is destroyed if:

• A. The magnet is heated.
• B. The magnet is thrown.
• C. The magnet is broken into pieces.
• D. Opposite poles of two magnets are kept together.

Answer 1

Answer: (A), (B), (C)

The correct options are
A The magnet is heated.
B The magnet is thrown.
C The magnet is broken into pieces.

The magnetism of a magnet is destroyed when heated, thrown or broken into pieces. These activities demagnetize the magnet easily.
Keeping the opposite poles of two magnets together can save the loss of magnetism.
