The arrangement to store two magnets is shown by figures (a), (b), (c) and (d) in Fig. 13.2. Which one of them is the correct arrangement

Options

A.
B.
C.
D.

Explanation

To determine the correct arrangement for storing two magnets from the given options (a), (b), (c), and (d), we need to analyze each arrangement based on the principles of magnetism.

### Step-by-Step Solution:

1. **Understanding Magnet Poles**: Magnets have two poles: North (N) and South (S). Like poles repel each other (N-N or S-S), while unlike poles attract each other (N-S).

2. **Analyzing Option (a)**: In this arrangement, if the two magnets are placed with like poles facing each other (e.g., N-N or S-S), they will repel each other. This is not a stable arrangement for storage.

3. **Analyzing Option (b)**: In this arrangement, if the magnets are placed with unlike poles facing each other (e.g., N-S), they will attract each other. This creates a stable arrangement, preventing them from falling apart.

4. **Analyzing Option (c)**: If this arrangement has the magnets placed with like poles facing each other, similar to option (a), they will repel and not stay together. This is also not a correct arrangement for storage.

5. **Analyzing Option (d)**: If this option has the magnets placed in a way that they are not secured by a wooden block or have the wrong pole orientation, then it is also an incorrect arrangement.

6. **Conclusion**: The correct arrangement for storing two magnets is the one where the unlike poles are facing each other, which is found in option (b). This ensures that the magnets are attracted to each other and remain stable.

### Final Answer:
The correct arrangement for storing two magnets is **option (b)**, where the unlike poles are facing each other.
