Question

If a permanent magnet is struck with a hammer, it will lose some of its magnetism; each subsequent blow helps the molecules return to their original random positions. True/False

A) True
B) False

Answer 1

False. When a permanent magnet is struck with a hammer, it may lose some of its magnetism temporarily, but it does not lose its ability to be a magnet permanently.

Step-by-step explanation:

The statement is False.

When a permanent magnet is struck with a hammer, it may lose some of its magnetism temporarily, but it does not lose its ability to be a magnet permanently. The molecules in a magnet are aligned in specific patterns called domains, and external factors like striking or heating can disrupt these patterns and cause the magnetism to weaken. However, the molecules will gradually return to their original positions, and the magnetism will be restored over time.

To permanently demagnetize a magnet, hard blows or heating it in the absence of another magnet are required.
