Assertion : Most of the iron filings stick to the magnet at the ends.
Reason : Magnetic strength is maximum on the poles of a magnet.

Options

A. If both assertion and reason are true and reason is the correct explanation of assertion.
B. If both assertion and reason are true but reason is not the correct explanation of assertion.
C. If assertion is true but reason is false.
D. If assertion is false but reason is true.

Explanation

To analyze the assertion and reason provided in the question, we can break it down step by step.

### Step 1: Understanding the Assertion
The assertion states that "Most of the iron filings stick to the magnet at the ends." This means that when iron filings are scattered around a magnet, they tend to accumulate more at the ends (or poles) of the magnet rather than in the middle.

### Step 2: Understanding the Reason
The reason given is that "Magnetic strength is maximum on the poles of a magnet." This implies that the areas at the ends of the magnet (the north and south poles) have a stronger magnetic force compared to the middle of the magnet.

### Step 3: Analyzing the Relationship
Now, we need to see if the reason supports the assertion. Since it is a known fact in physics that the magnetic field strength is indeed strongest at the poles of a magnet, it logically follows that iron filings would be attracted more strongly to these areas. Therefore, the assertion is supported by the reason.

### Step 4: Conclusion
Both the assertion and the reason are true. Furthermore, the reason provided is a correct explanation for the assertion. Thus, we can conclude that:

- Assertion: True
- Reason: True
- The reason is a correct explanation of the assertion.

### Final Answer
Both the assertion and the reason are true, and the reason is the correct explanation for the assertion.
