Assertion When two magnets are brought closer to each other, then they will always repel each other.
Reason According to Lanz's law induced effects always opposes the cause.

Options

A. If both Assertion and Reason are corrent and Reason is the corrent explanation of Assertion.
B. If both Assertion and Reason are correct 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 ture.

Explanation

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

### Step 1: Understand the Assertion
The assertion states: "When two magnets are brought closer to each other, then they will always repel each other."

- **Analysis**: This statement is incorrect. When two magnets are brought closer, they can either attract or repel each other depending on the orientation of their poles. If a north pole of one magnet is brought close to the south pole of another magnet, they will attract each other. Therefore, the assertion is false.

### Step 2: Understand the Reason
The reason states: "According to Lenz's law, induced effects always oppose the cause."

- **Analysis**: Lenz's law is a principle in electromagnetism that states that the direction of an induced current is such that it opposes the change in magnetic flux that produced it. This statement is true and accurately describes Lenz's law.

### Step 3: Conclusion
Now, we can conclude the relationship between the assertion and the reason:

- The assertion is false because magnets do not always repel each other; they can also attract.
- The reason is true as it correctly states Lenz's law.

### Final Answer
Since the assertion is false and the reason is true, the correct option is:
**D: Assertion is false but Reason is true.**
