Assertion : Artificial magnets are also known as permanent magnets since their magnetism persists for long time.
Reason : In hospitals, strong magnets are used to remove iron or steel splinters from patients eye or other parts of the body.

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 explation of assertion.
C. If assertion is true but reason is false
D. If assertion is false but reason is true.

Answer

To solve the question, we need to analyze both the assertion and the reason provided.

### Step 1: Analyze the Assertion
The assertion states that "Artificial magnets are also known as permanent magnets since their magnetism persists for a long time."

- **Explanation**: Artificial magnets, such as bar magnets, are made from materials that can retain their magnetism over time. This is true; artificial magnets are designed to maintain their magnetic properties for an extended period, similar to permanent magnets.

### Step 2: Analyze the Reason
The reason states that "In hospitals, strong magnets are used to remove iron or steel splinters from patients' eyes or other parts of the body."

- **Explanation**: This statement is also true. Strong magnets can attract iron or steel splinters, making it easier to remove them from the body. This is a practical application of magnetism in medicine.

### Step 3: Determine the Relationship
Now we need to determine if the reason correctly explains the assertion.

- The assertion is about the nature of artificial magnets and their long-lasting magnetism.
- The reason discusses the application of magnets in a medical context.

### Conclusion
Both the assertion and the reason are true, but the reason does not provide a correct explanation for the assertion. The assertion is based on the properties of artificial magnets, while the reason is about their application in a specific scenario.

### Final Answer
The correct option is: **Both assertion and reason are true, but the reason is not the correct explanation of the assertion.**
