The correct Answer is:
To solve the given assertion and reason question, we need to analyze both statements carefully. ### Step 1: Analyze the Assertion **Assertion**: Magnetic field interacts with a moving charge and not with a stationary charge. - A magnetic field does indeed interact with moving charges. When a charge is stationary, it does not experience a force due to a magnetic field because the magnetic force is given by the equation \( F = q(\mathbf{v} \times \mathbf{B}) \), where \( \mathbf{v} \) is the velocity of the charge and \( \mathbf{B} \) is the magnetic field. If the charge is stationary, \( \mathbf{v} = 0 \) and thus \( F = 0 \). - Therefore, the assertion is **True**. ### Step 2: Analyze the Reason **Reason**: A moving charge produces a magnetic field. - A moving charge does indeed produce a magnetic field. This is a fundamental principle of electromagnetism. When a charge moves, it creates a magnetic field around it, which can interact with other charges or magnetic fields. - Therefore, the reason is also **True**. ### Step 3: Determine the Relationship between Assertion and Reason - The assertion states that a magnetic field interacts with moving charges, which is true. The reason states that a moving charge produces a magnetic field, which is also true. - Furthermore, the reason provides a correct explanation for the assertion because the interaction of the magnetic field with the moving charge is due to the magnetic field produced by the moving charge itself. ### Conclusion Since both the assertion and reason are true, and the reason correctly explains the assertion, the correct answer is: **(A) If both Assertion & Reason are True & the Reason is a correct explanation of the Assertion.** ---
