Assertion (A): By lamination of metal, eddy currents can be minimized.
Reason (R): To cut eddy currents specific arrangements are required.

Options

A. Both (A) and (R) are true and (R) is the correct explanation of (A).
B. Both (A) and (R) are true but (R) is not the correct explanation of (A).
C. (A) is true but (R) is false.
D. (A) is false and (R) is also false.

Explanation

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

### Step 1: Understand the Assertion
The assertion states that "By lamination of metal, eddy currents can be minimized."

**Explanation:**
Lamination involves stacking thin sheets of metal together, which increases the resistance to the flow of eddy currents. Eddy currents are loops of electrical current that are induced within conductors by a changing magnetic field. By using laminated sheets, the paths available for these currents are reduced, thus minimizing their magnitude.

### Step 2: Understand the Reason
The reason states that "To cut eddy currents, specific arrangements are required."

**Explanation:**
To effectively minimize eddy currents, specific arrangements such as the lamination of metal sheets are necessary. These arrangements disrupt the flow of eddy currents by increasing the electrical resistance and reducing the area available for the currents to circulate.

### Step 3: Evaluate the Relationship Between Assertion and Reason
We need to determine if the reason supports the assertion.

**Analysis:**
- The assertion is correct: Lamination does minimize eddy currents.
- The reason is also correct: Specific arrangements, such as lamination, are indeed required to achieve this minimization.

### Step 4: Conclusion
Both the assertion and the reason are true, and the reason correctly explains why the assertion is true. Therefore, we can conclude that both the assertion and the reason are valid.

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