Question

question 9

if a permanent magnet is cut into pieces, each piece ______ a separate magnet.
a. is
b. is not

Explanation:

Understand the behavior of permanent magnets

Using the Magnetic Domains knowledge point

$$ \text{A permanent magnet consists of aligned microscopic magnetic domains.} $$

Analyze the effect of cutting a magnet

When a permanent magnet is cut into smaller pieces, the internal alignment of the magnetic domains remains intact. Each individual piece retains its own north and south poles, meaning it behaves as a complete, independent magnet.

Select the correct option

Since each piece becomes a complete magnet with its own north and south poles, each piece is a separate magnet. This corresponds to option a.

Answer:

• a. is (Correct answer)
• b. is not
