A: If different ends of two identical looking iron bars are brought closer and they always attract each other then one of the bars is not magnetized.
R: Repulsion is the sure check of presence od magnetization of both the bars.

Options

A. If both Assertion & Reason are the true and the reason is the correct explanation of the assertion, then mark (1)
B. If both Assertion & Reason are true but the reson is not the correct explanation of the assertion, then mark (2)
C. If Assertion is true statement but Reason is false, then mark (3)
D. If both Assertion and Reason are false statements, then mark (4)

Answer

To solve the problem, we need to analyze the assertion (A) and reason (R) given in the question step by step.

### Step 1: Understanding the Assertion (A)
The assertion states that if the different ends of two identical-looking iron bars are brought closer and they always attract each other, then one of the bars is not magnetized.

- **Analysis**:
- If both bars were magnetized, they would have distinct poles (North and South).
- When you bring the North pole of one bar close to the North pole of another, they would repel each other.
- Similarly, if both bars were South poles, they would also repel each other.
- Therefore, if they always attract, it indicates that at least one of the bars must be non-magnetized.

### Step 2: Understanding the Reason (R)
The reason states that repulsion is the sure check of the presence of magnetization in both bars.

- **Analysis**:
- This is true because if both bars are magnetized, they will have opposite poles that attract each other and like poles that repel each other.
- If you observe repulsion, it confirms that both bars are magnetized since like poles are repelling each other.
- Thus, if there is no repulsion observed, it indicates that at least one of the bars is not magnetized.

### Step 3: Conclusion
Both the assertion and the reason are correct. The assertion correctly states the condition under which the bars attract, and the reason explains the relationship between magnetization and the behavior of the bars.

### Final Answer
Both the assertion (A) and reason (R) are correct, and the reason correctly explains the assertion.
